the use of equipment in ilmenite mining process

Ilmenite is one of the most important ores of the metal titanium in the world. It is mined as an important industrial mineral in several deposits throughout the world, and many of them are in placer sands. Ilmenite is very similar in structure to Hematite, and is essentially the same as Hematite with roughly half the iron replaced with titanium. Ilmenite is a weakly magnetic titanium-iron oxide mineral which is iron-black or steel-gray. Most ilmenite is mined for titanium dioxide production.Ilmenite is a titanium bearing mineral that, directly or indirectly, supplies in excess of 90% of the feedstock to the large titanium dioxide pigment industry as well as to the very significant and growing titanium metal market and some smaller industrial applications.

In the ilmenite raw ore crushing process, we need to use the crusher. Shanghai shibang company can provide different types of crusher for choosing which refers to the crushing machine used for dealing with large ilmenite stones. Like jaw crusher, impact crusher and cone crusher. You can choose one or two crushers to compose of your ilmenite mining production line.

PE series jaw crusher is usually used as primary crusher in quarry production lines, mineral ore crushing plants and powder making plants. It manufactured with world-class manufacturing technology and advanced digital parts processing equipment to ensure the precision of the machine parts. Choosing the best production material, greatly enhance the compressive resistance, wear resistance and greatly prolong the service life of the machine.

PF series impact crusher can be used to deal with materials whose size below 500mm and whose compression strength less than 360Mpa. It has high grinding efficiency, the rotational inertia of the rotor has a large and low energy consumption; The top of the machine is equipped with discharging mouth adjusting device which can be simple and quick adjustment counterattack plate and plate hammer gap and control the size of discharge; Product shape is a cube, no tension fracture. Grain shape is good. According to the standard of all kinds of sand and gravel aggregate level, it is suitable. Also it has simple structure and convenient in maintenance.

Apart from crushing equipment, we also need conveyorbeltinilmenitemining processing which will be used in composing of conveying system. Conveyor belt for ilmenite mining is available with either rollersor a solid surface to support the carrying belt. When ilmenite stones fall down on the conveyor, the roller under the belt will drive the belt come forward. In this way, conveyor belt can transfer materials continuously and evenly.

Most ilmenite ore are poor ilmenite ore, so the ore processing must be carried out. Ilmenite ore beneficiation methods currently used for the mechanical selection (including washing, screening, re-election, high intensity magnetic separation and flotation), as well as fire enrichment, chemical processing method. During the whole production line, electric separation, gravity separation and strong magnetic separation, flotation separation and roasting separation are all the necessary steps.

The ilmenite mining process includes gravity separation, magnetic separation and electric separation. Firstly, the raw materials should be extracted from the mine. After this step, the concentrated mines which contain the gravity materials will get. You can get the ilmenite with the help of middle strong magnetic separation. The strong magnetic will recover the monazite and the shaking table is used to remove the gangue. The electric separation is mainly used for separating the rutile with zircon.

Ilmenite is brittle and dense. Due to the physical and chemical properties of the mineral surface, it is not easy to recover coarse-grained ilmenite, but fine-grained or fine-grained ilmenite has better floatability and can be recovered by flotation.

When using conventional flotation methods for beneficiation, oleic acid and its soaps are commonly used. The application technology of this collector is very mature and it is more reliable in application. However, it also has a major disadvantage, that is, the amount of material used is too large. Oxidized paraffin soap is a substance obtained by saponification of paraffin after oxidation. This collector has a wider source and is more cost-effective and can replace oleic acid and its soaps to some extent. The beneficiation efficiency of the collector is relatively poor, and the grade of the selected minerals obtained is not stable enough. Tahr oil is the acidification product of Tahr soap. Compared with oxidized paraffin wax soap, the ore grade selected by this collector is more stable. However, it needs to be emulsified to ensure its collection effect before proceeding. Compared with the above conventional collectors, the new ilmenite collector has better selectivity, generally does not need to be emulsified, and has a better separation effect for some difficult-to-separate minerals.

It can be subdivided into selective flocculation and hydrophobic flocculation. Among them, selective flocculation refers to the first coagulation of a single mineral in a mixture composed of two or more minerals, and then gradually separating them. The hydrophobic flocculation method uses the hydrophobic interaction between the hydrophobic particles suspended in water to attract each other and aggregate them, and then separate them. This method can increase the grade of the original ore from less than 10% at the beginning to 40% to 50%, and greatly increase the efficiency of recycling to reach or even exceed 50%.

Used for agglomeration flotation of ilmenite, it means to make the ilmenite hydrophobic by the collector adsorbed on the surface of the ilmenite, and then use the capillary attraction of the bridge liquid to agglomerate the ore particles, and then separate them after floating.It should be noted that in the process of beneficiation with agglomeration flotation, the strength and strength of the stirring must be ensured at all times, so that the ore particles can be more easily aggregated into agglomerates to achieve the effect of selection. When agglomerate flotation is used to recover titanium, it is recommended to use sodium oleate 3.5 kg/ton as collector and 1.5 kg/ton oxalic acid as inhibitor. After agglomeration flotation method, the grade of the concentrate can reach more than 45%, and the recovery rate can reach or exceed 75%. However, if the stirring strength is not enough, the recovery rate may drop by 4% to 5% or more. In addition, the diameter of the impeller and its position in the tank will also affect the flotation index. When the diameter of the impeller reaches about 50% of the diameter of the stirring tank and the impeller is about one meter from the bottom of the tank, the effect of agglomeration flotation will be better.

major equipment in the whole process of quartzite mining plant

In recent years, with the increasingly high-grade of glass, ceramics, metallurgy, foundry industry, there is more and moredemand on quartz sandstone. Quartz is a very common in sedimentary rocks and it is also present in variable amounts as an accessory mineral in most carbonate rocks. Additionally it is a standard constituent of schist, gneiss, quartzite and other metamorphic rocks. Because of its capacity weathering, its very common in stream sediments plus residual soils. Quartz sandstone Fe2O3 content is generally high; besides high quality quartz sandstone reserves are low. So the processing of quartz has highly valued by enterprises. Quartzmining process has made a number of technology transformations.

The main process in quartzite mining plant mainly includes crushing, grinding, grading, flotation. Due to the high demand on the quality of fine quartz sand, quartz prices are also rising. Quartzite ore mining process is directly related to the quality of quartz sand. We all know that, crushing and grinding process is important in quartz sand making process, glass and ceramics production line. Inquartzite mining plant, at first, quartzite is crushed by jaw crusher, and thenquartzite would enter into impact crusher or cone crusher for the second crushing process. After that, through vibrating screen, these quartzite particles are sizing according to different size. In quartzite grinding process, quartzite is grinded into powder by quartz grinding machine. Through the investigation of the world quartzite mining plant, we have combined with the actual situation of enterprises; we adopt the most advanced processing technology, in order to meet the quality requirements of fine quartz sand. Ball mill, vertical mill, ultrafine mill is usually used in this process. The finished quartzite powder can be upto 2500 mesh. SBM is a professional quartzite crushing and milling equipment manufacturer in China, which can supplies types of quartzite crushing machines, screen and belt conveyor for sale. SBM can provide high-efficiency crushing and milling production equipment for you.

In order to ensure the quality of quartz sand, sieving equipment in quartzite processing plant has a very obvious role. The vibrating screen is a kind of sieving equipment of international advanced level, which developed by our company on the basis of carrying on the advantages of traditional screening equipment and absorbing the outstanding technology from abroad. SBM vibrating screenare installed in about 130 countries of the global market.In the weathering and mining process of quartz sand, a large amount of clay minerals and iron minerals will form cement or adhesion minerals on the surface of silica. Therefore, we usually use screening equipment inquartzite processing plant to improve the quartzite ore quality. Thescreening process serves as pretreatment of sand separation, in which clay impurities will be cleaned efficiently. Choosing high-efficiency screening equipment in quartzite processing plantis the key in the production of high quality quartz sand.

Quartzite mining plant should have a flotation process which needs flotation machine with optimistic structure design. Now there are many kinds of flotation machines, such as agitator flotation machine, pneumatic flotation machine and pneumatic-agitator flotation machine. By using flotation machine, we can enhance the performance of scrubbing in the screening process. For further separation of quartz sand, the flotation process can dispose of feldspar, with hydrofluoric acid being the most commonly used liquid in overseas market. Flotation machine are mainly used in quartzite mining plant, selecting the valuable mine from gangue. Through the introduction above, we summed up the whole process of quartzitemining plant, which has an important influence on the comprehensive application ofquartzite.

Titanium is a chemical element with the symbol Ti and atomic number 22. It is a lustrous transition metal with a silver color, low density, and high strength. Titanium is resistant to corrosion in sea water, aqua regia, and chlorine.

Titanium is the ninth-most abundant element in Earths crust (0.63% by mass) and the seventh-most abundant metal. It is present as oxides in most igneous rocks, in sediments derived from them, in living things, and natural bodies of water. Of the 801 types of igneous rocks analyzed by the United States Geological Survey, 784 contained titanium. Its proportion of soils is approximately 0.5 to 1.5%.

Common titanium-containing minerals are anatase, brookite, ilmenite, perovskite, rutile, and titanite (sphene). Akaogiite is an extremely rare mineral consisting of titanium dioxide. Of these minerals, only rutile and ilmenite have economic importance, yet even they are difficult to find in high concentrations. About 6.0 and 0.7 million tonnes of those minerals were mined in 2011, respectively. Significant titanium-bearing ilmenite deposits exist in western Australia, Canada, China, India, Mozambique, New Zealand, Norway, Sierra Leone, South Africa, and Ukraine. About 186,000 tonnes of titanium metal sponge were produced in 2011, mostly in China (60,000 t), Japan (56,000 t), Russia (40,000 t), United States (32,000 t) and Kazakhstan (20,700 t). Total reserves of titanium are estimated to exceed 600 million tonnes.

Titanium can be alloyed with iron, aluminum, vanadium, and molybdenum, among other elements, to produce strong, lightweight alloys for aerospace (jet engines, missiles, and spacecraft), military, industrial processes (chemicals and petrochemicals, desalination plants, pulp, and paper), automotive, agriculture (farming), medical prostheses, orthopedic implants, dental and endodontic instruments and files, dental implants, sporting goods, jewelry, mobile phones, and other applications.
