India has the potential to produce $400-500 billion worth of oil and gas, gold, silver, iron ore, copper, coal, calcium, rock phosphate and others. It is bound to generate substantial revenues for the government, which will be helpful in developing infrastructure for the country.
This will also create employment for 10-15 crore people, by setting up over thousands of new large, medium and small scale industries for processing natural resources. The GDP will improve and the current account deficit will come down, making it a win-win situation for all.
India is blessed with iron ore reserves, like Australia and Brazil, but the difference in production and outlook is immeasurable. Except iron ore, India also has abundant many other types of minerals, such as coal, bauxite, copper, limestone etc. Mining is the only sector with the true potential to make India an economic powerhouse.
Mining operation involves many different operations, including drilling, blasting, extraction, quarrying, crushing, grinding, screening, conveying, separation, processing etc. Crushing is the primary and integral operation in mining industry. Stone crushing can be operated in three stages according to production requirements. SBM provides complete range of crushing machine for mining plant and mobile stone crusher in India.

challenges and opportunities in the iron ore crusher market | industrial vehicle technology international
January 25, 2019, the Vale iron mine in Brazil experienced a dam break, which led to the closure of large-scale mines. At the same time, the two major mines in Australia, BHP and Rio Tinto, were affected by the hurricane to reduce their shipments.
Since the end of January this year, iron ore prices have risen sharply, far exceeding the increase in steel and other raw materials. Therefore, iron ore has become the most popular investment in the eyes of investors. In July 2019, the price of iron ore reached more than US$120 per ton.
For the time being, the investment prospect of iron ore is very bright. So what is the global reserves and distribution of iron ore? How much does it cost to build an iron ore processing line? This article will answer you in detail.
The data released by USGS in early 2005 showed that the global iron ore reserves were 160 billion tons, the reserves of mineral iron (ie, iron contained in iron ore) were 80 billion tons and the basic reserves were 180 billion tons.
The worlds iron ore is mainly reserved in Ukraine, Russia, Brazil, China and Australia. The reserves are 30 billion tons, 25 billion tons, 21 billion tons, 21 billion tons and 18 billion tons respectively, accounting for 18.8%, 15.6%, 13.1%, 13.1% and 11.3% of the worlds total reserves respectively.
In addition, Kazakhstan, the United States, India, Venezuela and Sweden also have rich iron ore resources, and their iron ore reserves are 8.3 billion tons, 6.9 billion tons, 6.6 billion tons, 4 billion tons and 3.5 billion tons, respectively accounting for 5.2%, 4.3%, 4.1%, 2.5% and 2.2% of the worlds total iron ore reserves.
The worlds mineral iron is mainly reserved in Brazil, Russia and Australia, with reserves of 14 billion tons, 14 billion tons and 11 billion tons respectively, accounting for 17.5%, 17.5% and 13.8% of the worlds total reserves. The sum of the reserves in the three countries accounts for 48.8% of the total reserves in the world.
Mineral iron reserves and basic reserves are the most representative of the richness of a countrys iron ore resources, so Brazil, Russia and Australia are the worlds richest iron ore resources. At the same time, it shows that although Ukraine and China have large reserves of iron ore, they have more lean ore and less rich ore.
Iron ore resources are mainly reserved in more than10 countries, and 90% of proven reserves are distributed in10 countries and regions. They are: CIS (proven reserves of 114 billion tons, of which Russia is more than 80 billion tons), Brazil (68 billion tons), China (50 billion tons), Canada (over 36 billion tons), Australia (35 billion tons) ), India (17.57 billion tons), the United States (17.4 billion tons), France (7 billion tons), Sweden (3.65 billion tons).
The global iron mine reserves increased from 232 billion tons in 1996 to 370 billion tons in 2006, an increase of 59.5% in 10 years. The total amount of iron ore resources in the world is estimated to exceed 800 billion tons (the amount of iron ore), and the iron content exceeds 230 billion tons and there is still great potential for future discovery.
The major countries of iron ore resources include Brazil, Australia, China, Russia, Kazakhstan, Ukraine, the United States, India, Sweden, and Venezuela. High-grade ore is widely distributed in Brazil, Australia, India and other countries. The low mining cost and relatively high grade of iron ore make these countries the major iron ore suppliers in the world.
Before dry selection, the lean iron ore requires millimeter-scale fine crushing by the fine crusher. If the particle size of the iron ore is not small enough in the crushing stage, low-grade iron ore is difficult to be selected later, which will cause serious waste of resources.
The common problem in the iron ore crushing production line is that the wear parts of the fine crusher are seriously worn out, and the repair and maintenance of the fine crusher are too frequent, which makes the production efficiency of the iron ore crushing production line lower.
Different iron ore has different features. According to these features, the crushers are made of different materials. Therefore, the prices of iron ore crusher are different. However, reasonable crushing processes and crusher can be used to save the cost investment and achieve the required crushing effect.
In the crushing process of lean iron ore, in order to obtain the best process configuration and the lowest crushing cost, it is necessary to master the relationship of particle size among the primary crushing, the secondary crushing and the fine crushing.
For medium and low hardness lean iron ore, the second crushing equipment can use the impact crusher. The iron ore impact crusher utilizes a plate hammer on a high-speed moving rotor to produce a high-speed impact on the iron ore fed into the crushing chamber. The crushed iron ore is thrown at a high speed in the tangential direction toward the counter-attack at the other end of the crushing chamber.
During this process, the iron ore will collide with each other, causing cracks and looseness. When the iron ore particle size is smaller than the gap between the counterattack plate and the plate hammer, it is discharged outside the machine.
For high-hardness iron ore, a cone crusher can be used for the secondary crushing equipment. The HXJQ short-headed cone crusher can achieve a fine crushing effect of 3 to 13mm, which can fully meet the requirements of dry selection and grinding. However, due to the high hardness of such iron ore, the impact on the wear parts is large, so ordinary crushing equipment is difficult to exert its advantage.
In areas with low power consumption, the sand making machine developed and produced by HXJQ can achieve the fine crushing effect of high hardness and high output iron ore. Not only can the iron ore particle size be reduced to improve the dry selection efficiency, but also the ball mill load and operating cost can be greatly reduced, and the ball mill production capacity can be improved.
The price of iron ore crushing production line is related to various factors such as equipment combination, output level, and quality. Of course, the quotation standards of different manufacturers will also be different. Customers also need to analyze specifically when purchasing.
The comparison found that the price of the iron ore crushing production line of HXJQ Machinery is the most economical and reasonable, ensuring that the production line has a long service life, less failure, high efficiency, good effect, energy-saving and environmental protection, and can keep its price lower than other manufacturers 6% to 7%.
At the same time, the HXJQ configuration plan is all-sided, and there is a wide variety of equipment in HXJQ Machinery. If you are interested in these crushing equipment, please submit your relevant information on the right side, we will arrange a professional engineer to answer your questions.

After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore. The beneficiation process should be as efficient and simple as possible, such as the development of energy-saving equipment, and the best possible results with the most suitable process. In the iron ore beneficiation factory, the equipment investment, production cost, power consumption and steel consumption of crushing and grinding operations often account for the largest proportion. Therefore, the calculation and selection of crushing and grinding equipment and the quality of operation management are to a large extent determine the economic benefits of the beneficiation factory.
There are many types of iron ore, but mainly magnetite (Fe3O4) and hematite (Fe2O3) are used for iron production because magnetite and hematite have higher content of iron and easy to be upgraded to high grade for steel factories.
Due to the deformation of the geological properties, there would be some changes of the characteristics of the raw ore and sometimes magnetite, hematite, limonite as well as other types iron ore and veins are in symbiosis form. So mineralogy study on the forms, characteristics as well as liberation size are necessary before getting into the study of beneficiation technology.
1. Magnetite ore stage grinding-magnetic separation process
The stage grinding-magnetic separation process mainly utilizes the characteristics of magnetite that can be enriched under coarse grinding conditions, and at the same time, it can discharge the characteristics of single gangue, reducing the amount of grinding in the next stage.
In the process of continuous development and improvement, the process adopts high-efficiency magnetic separation equipment to achieve energy saving and consumption reduction. At present, almost all magnetic separation plants in China use a large-diameter (medium 1 050 mm, medium 1 200 mm, medium 1 500 mm, etc.) permanent magnet magnetic separator to carry out the stage tailing removing process after one stage grinding. The characteristic of permanent magnet large-diameter magnetic separator is that it can effectively separate 3~0mm or 6~0mm, or even 10-0mm coarse-grained magnetite ore, and the yield of removed tails is generally 30.00%~50.00%. The grade is below 8.00%, which creates good conditions for the magnetic separation plant to save energy and increase production.
2.Magnetic separation-fine screen process
Gangue conjoined bodies such as magnetite and quartz can be enriched when the particle size and magnetic properties reach a certain range. However, it is easy to form a coarse concatenated mixture in the iron concentrate, which reduces the grade of the iron concentrate. This kind of concentrate is sieved by a fine sieve with corresponding sieve holes, and high-quality iron concentrate can be obtained under the sieve.
There are two methods for gravity separation of hematite. One is coarse-grained gravity separation. The geological grade of the ore deposit is relatively high (about 50%), but the ore body is thinner or has more interlayers. The waste rock is mixed in during mining to dilute the ore. For this kind of ore, only crushing and no-grinding can be used so coarse-grained tailings are discarded through re-election to recover the geological grade.
The other one is fine-grain gravity separation, which mostly deals with the hematite with finer grain size and high magnetic content. After crushing, the ore is ground to separate the mineral monomers, and the fine-grained high-grade concentrate is obtained by gravity separation. However, since most of the weak magnetic iron ore concentrates with strong magnetic separation are not high in grade, and the unit processing capacity of the gravity separation process is relatively low, the combined process of strong magnetic separation and gravity separation is often used, that is, the strong magnetic separation process is used to discard a large amount of unqualified tailings, and then use the gravity separation process to further process the strong magnetic concentrate to improve the concentrate grade.
Due to the complexity, large-scale mixed iron ore and hematite ore adopt stage grinding or continuous grinding, coarse subdivision separation, gravity separation-weak magnetic separation-high gradient magnetic separation-anion reverse flotation process. The characteristics of such process are as follows:
(1) Coarse subdivision separation: For the coarse part, use gravity separation to take out most of the coarse-grained iron concentrate after a stage of grinding. The SLon type high gradient medium magnetic machine removes part of the tailings; the fine part uses the SLon type high gradient strong magnetic separator to further remove the tailings and mud to create good operating conditions for reverse flotation. Due to the superior performance of the SLon-type high-gradient magnetic separator, a higher recovery rate in the whole process is ensured, and the reverse flotation guarantees a higher fine-grained concentrate grade.
(2) A reasonable process for narrow-level selection is realized. In the process of mineral separation, the degree of separation of minerals is not only related to the characteristics of the mineral itself, but also to the specific surface area of the mineral particles. This effect is more prominent in the flotation process. Because in the flotation process, the minimum value of the force between the flotation agent and the mineral and the agent and the bubble is related to the specific surface area of the mineral, and the ratio of the agent to the mineral action area. This makes the factors double affecting the floatability of minerals easily causing minerals with a large specific surface area and relatively difficult to float and minerals with a small specific surface area and relatively easy to float have relatively consistent floatability, and sometimes the former has even better floatability. The realization of the narrow-level beneficiation process can prevent the occurrence of the above-mentioned phenomenon that easily leads to the chaos of the flotation process to a large extent, and improve the beneficiation efficiency.
(3) The combined application of high-gradient strong magnetic separation and anion reverse flotation process achieves the best combination of processes. At present, the weak magnetic iron ore beneficiation plants in China all adopt high-gradient strong magnetic separation-anion reverse flotation process in their technological process. This combination is particularly effective in the beneficiation of weak magnetic iron ore. For high-gradient strong magnetic separation, the effect of improving the grade of concentrate is not obvious. However, it is very effective to rely on high-gradient and strong magnetic separation to provide ideal raw materials for reverse flotation. At the same time, anion reverse flotation is affected by its own process characteristics and is particularly effective for the separation of fine-grained and relatively high-grade materials. The advantages of high-gradient strong magnetic separation and anion reverse flotation technology complement each other, and realize the delicate combination of the beneficiation process.
The key technology innovation of the integrated dry grinding and magnetic separation system is to "replace ball mill grinding with HPGR grinding", and the target is to reduce the cost of ball mill grinding and wet magnetic separation.
HPGRs orhigh-pressure grinding rollshave made broad advances into mining industries. The technology is now widely viewed as a primary milling alternative, and there are several large installations commissioned in recent years. After these developments, anHPGRsbased circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.
The wear on a rolls surface is a function of the ores abrasivity. Increasing roll speed or pressure increases wear with a given material. Studs allowing the formation of an autogenous wear layer, edge blocks, and cheek plates. Development in these areas continues, with examples including profiling of stud hardness to minimize the bathtub effect (wear of the center of the rolls more rapidly than the outer areas), low-profile edge blocks for installation on worn tires, and improvements in both design and wear materials for cheek plates.
With Strip Surface, HPGRs improve observed downstream comminution efficiency. This is attributable to both increased fines generation, but also due to what appears to be weakening of the ore which many researchers attribute to micro-cracking.
As we tested , the average yield of 3mm-0 and 0.15mm-0 size fraction with Strip Surface was 78.3% and 46.2%, comparatively, the average yield of 3mm-0 and 0.3mm-0 with studs surface was 58.36% and 21.7%.
These intelligently engineered units are ideal for classifying coarser cuts ranging from 50 to 200 mesh. The feed material is dropped into the top of the classifier. It falls into a continuous feed curtain in front of the vanes, passing through low velocity air entering the side of the unit. The air flow direction is changed by the vanes from horizontal to angularly upward, resulting in separation and classification of the particulate. Coarse particles dropps directly to the product and fine particles are efficiently discharged through a valve beneath the unit. The micro fines are conveyed by air to a fabric filter for final recovery.
Air Magnetic Separation Cluster is a special equipment developed for dry magnetic separation of fine size (-3mm) and micro fine size(-0.1mm) magnetite. The air magnetic separation system can be combined according to the characteristic of magnetic minerals to achieve effective recovery of magnetite.
After rough grinding, adopt appropriate separation method, discard part of tailings and sort out part of qualified concentrate, and re-grind and re-separate the middling, is called stage grinding and stage separation process.
According to the characteristics of the raw ore, the use of stage grinding and stage separation technology is an effective measure for energy conservation in iron ore concentrators. At the coarser one-stage grinding fineness, high-efficiency beneficiation equipment is used to advance the tailings, which greatly reduces the processing volume of the second-stage grinding.
If the crystal grain size is relatively coarse, the stage grinding, stage magnetic separation-fine sieve self-circulation process is adopted. Generally, the product on the fine sieve is given to the second stage grinding and re-grinding. The process flow is relatively simple.
If the crystal grain size is too fine, the process of stage grinding, stage magnetic separation and fine sieve regrind is adopted. This process is the third stage of grinding and fine grinding after the products on the first and second stages of fine sieve are concentrated and magnetically separated. Then it is processed by magnetic separation and fine sieve, the process is relatively complicated.
At present, the operation of magnetic separation (including weak magnetic separation and strong magnetic separation) is one of the effective means of throwing tails in advance; anion reverse flotation and cation reverse flotation are one of the effective means to improve the grade of iron ore.
In particular, in the process of beneficiation, both of them basically take the selected feed minerals containing less gangue minerals as the sorting object, and both use the biggest difference in mineral selectivity, which makes the two in the whole process both play a good role in the process.
