The IGR 10K Placer Gold Mining Plant is an A-La-Carte = Fully Customized Alluvial Mining Equipment. This means that the user can order components from a list of existing part numbers without paying for engineering designs. The user can select options at the time of purchase or add components in the field without obsoleting the components they may already have. A 100 TPH (2400 Tons per day) gold recovery system.

As alluvial and eluvial deposits vary greatly in feed size distribution and clay content, an alluvial/eluvial plant needs the capacity to process an extreme range of conditions. It is common in the equatorial regions of the world to feed a plant with a dredge and/or an excavator. This plant can handle the range of material and various feed options.

The IGR 10K A-La-Carte Placer Gold Mining plant will have the versatility to process a broad spectrum of conditions from clean gravel to laterite and saprolite clays. Alluvial Channel/Gravel conditions may involve 20% to 90% of the solids feed passing 2mm- and continuing to the concentrators. Clays may have 90% passing 2mm- and continuing to the concentrators. This plant will work in conditions of both gravel and clay. Plant throughput and efficiency will vary with the condition of the material.

The A-La-Carte structure of the plant will allow the client to purchase only the components they need. The modular design will allow the purchaser or operator to add or remove components without obsoleting that which they already have and without requiring engineering design.

An operator may choose to start with or without the scrubber. This decision will be made based on knowledge of the clay content and capital investment. As the user gains experience they may choose to add the scrubber or remove it from their system; this is A-La-Carte the client can add or subtract components at will without re-design. Additionally, the user may desire to add options such as DMS or Jigs for diamonds and/or cyclones for dewatering/de-sliming.

The plant can be fed by excavator/loader or land dredge. Our plant including the scrubber is ideal to be fed by a loader/excavator. When feeding by a land dredge the user may opt to leave the scrubber out of the system. The land dredge will do a decent job of dispersing the clay though not perfect. The land dredge also delivers slurry at maybe 15% solids by weight. This is considered very thin slurry for efficient scrubbing. Operators in some regions insist on scrubbing the dredge discharge. Field testing will provide the best information on your material.

Sepro/IGR always recommend sample testing. Met-Solv Labs offers a specific lab test for laterite and saprolite clays We will write a performance guarantee for our equipment based on lab testing. This analysis will determine the ideal plant for your regional material.

An operator will feed material onto the grizzly. A water monitor fluidizes/mobilizes the material allowing it to pass through the grizzly where it continues to either a scrubber or vibrating screen. It is the fluidizing action of the monitor that controls the feed rate of solids into the system. Clean gravels will mobilize easily with the monitor and provide the maximum flow rate of solids. Clay will require more water to mobilize the material allowing it to pass through the grizzly. A wider grizzly allows larger clay balls to pass. This keeps the solids to water ratio high which leads to maximum efficiency in the scrubber and maximum solids throughput of the plant.

This wash plant scrubber works best at 50% solids. A scrubber uses large rock as the grinding media. A scrubber will lift the solids to 1 oclock and drop the solids back to 7 oclock causing an energy intensive lifting and dropping action. It is the attrition of the rock on rock action that acts to disperse the clay. Clay processing is based on energy input and retention time inside of the scrubber. To scrub better, the operator can increase the retention time or literally add large rocks to the scrubber.

After the scrubber the material passes to a double deck vibrating screen. Typically the upper deck cuts at 12mm and the lower deck cuts at 2mm. These can be specified by the customer. The 2mm- passes to a slurry transfer pump and on to the concentrators. The 2 to 12 mm middling is recombined with 12mm oversize and pass to the oversize stacking conveyor.

A max of 90 tph of solids can be fed to each battery without harm to the system. A minimum of 6 tph of solids is recommended to each battery. The intent is to always use 6 concentrators regardless of the feed rate. The slurry water capacity of 700 gpm +/-10% is intended to remain constant regardless of the solids feed rated. No control system is required for the slurry water.

A Carousel Distributor is used to distribute the slurry from the head tank to the 6 active concentrators. The distributor also blocks the flow to the 7th concentrator allowing the operator to rinse the rich concentrate. An operator will manually rotate the distributor and operate the valves on each concentrator.

Tails are piped to a common tails launder and with an 8 flanged outlet. The launder is designed for gravity discharge. (Pumping the tails requires modification to the depth of the launder to avoid cavitation.)

All equipment is mounted on a single skid designed to fit in a 20 container. The skid includes a roof structure with corrugate roofing. The container will arrive with the majority of the assembly already complete. Some site assembly will be required. This includes erection of the portions too tall to fit in the container and installation of the roof panels.

The screen fractions can be processed separately if the customer desires. This would require an additional conveyor. Also, one may choose alternate screen apertures: a top deck at 30mm where the 2mm to 30mm fraction is passed to a DMS or jig for diamonds is an option. In this case only the 30mm+ would pass to the tails conveyor.

Gold concentrators are batch machines. This means you must occasionally divert the feed to rinse the rich concentrate. In a system with only 1 concentrator, you either by-pass to tails or to a tank/slurry pump that recirculates the slurry back to a head tank. A system having 2 concentrators would allow to you to always feed 1 out of the 2. This is inefficient. A system feeding 2 concentrators while rinsing a third, becomes financially viable when using the economical i350. A battery feeding 6 while rinsing the 7th is very efficient and cost effective. The iCON Rotary Distributor allows easy distribution of the slurry and sequential rinsing without complicated industrial valves and/or controls. The distributor is hand operated.

rod mills

rod mills

A rod mill uses steel rods as the grinding media in tumbling mills is an efficient means to feed ball mills a product finer than could be made in a crusher but coarser than could be made in a ball mill. The principal use for rod mills, which were invented to make ball mill feed in a wet-grinding rod mill-ball mill circuit.

Rod mills came into use in the United States beginning in 1900s and eventually became recognized as efficient fine crushers. The 1st ever built rod mill (2 m in diameter by 4 m long) was to be installed at a mine where a coarser feed was required for shaking tables. Crushing rolls and rod mills were eventually used commonly to prepare feed to shaking tables. Later, rod mills of 2.9 m in diameter by 3.9 m long replaced most roll crushers.

With the increase in the diameter of rod mills, problems occurred in the shorter rod mills with rods tangling. When the rods were short relative to the diameter, some were lifted toward a vertical position, and continued tumbling caused tangling. This led to the arbitrary rule that the length of rods should be at least 1.5 times the mill diameter inside new shell liners.

The crushing action of the rod mass in a rod mill has been described and is illustrated in diagrams taken from his work in Figure 1. The progressive sizing of material from the feed to the discharge end of the mill by the tapered slot openings between the rods, and the resulting effective internal classification has been widely observed and documented. Apparently, the rod mass acts as an effective screen, holding back coarse particles from progressing along the length of the mill until crushed fine enough to pass along the slots. As well, the coarser particles tend to take the brunt of the rod impacts, and hold the rods apart, preventing the finer particles from being overground. These basic mechanisms ore consistently observable in the size distributions of rod mill products despite a multitude of other complex interactions taking place in the elevated charge, in the slurry pool, and due to the nature of the ore, slurry rheology, and mill design and operating variables. The historical trend towards producing a coarser rod mill discharge (equivalent to a higher feed rate per unit of mill power draw or volume) parallels the recognition of its natural preference to perform work on coarse material.

Energy efficiency in grinding is directly related to circuit economic performance because of the close interdependence of energy and media consumption, and their combined dominance of total direct grinding costs. Energy usage itself is the prime criterion by which grinding circuit process performance can be technically evaluated using the Bond Operating Work Index. As well, a knowledge of the possible range and nature of individual equipment energy consumption is required to determine the scope of possible changes in the process performance characteristics of each comminution stage. The following discussion therefore focuses on the effects of design or operating variables on both power draw and power efficiency, as well as giving consideration to some practical constraints for operating ease and stability.

rock crushers

rock crushers

The size requirement of the primary rock crusher is a function of grizzly openings, ore chute configuration, required throughput, ore moisture, and other factors. Usually, primary crushers are sized by the ability to accept the largest expected ore fragment. Jaw crushers are usually preferred as primary crushers in small installations due to the inherent mechanical simplicity and ease of operation of these machines. Additionally, jaw crushers wearing parts are relatively uncomplicated castings and tend to cost less per unit weight of metal than more complicated gyratory crusher castings. The primary crusher must be designed so that adequate surge capacity is present beneath the crusher. An ore stockpile after primary crushing is desirable but is not always possible to include in a compact design.

Many times the single heaviest equipment item in the entire plant is the primary crusher mainframe. The ability to transport the crusher main frame sometimes limits crusher size, particularly in remote locations having limited accessibility.

In a smaller installation, the crushing plant should be designed with the minimum number of required equipment items. Usually, a crushing plant that can process 1000s of metric tons per operating day will consist of a single primary crusher, a single screen, a single secondary cone crusher, and associated conveyor belts. The discharge from both primary and secondary crushers is directed to the screen. Screen oversize serves as feed to the secondary crusher while screen undersize is the finished product. For throughputs of 500 to 1,000 metric tons per operating day (usually 2 shifts), a closed circuit tertiary cone crusher is usually added to the crushing circuit outlined above. This approach, with the addition of a duplicate screen associated with the tertiary cone crusher, has proven to be effective even on ores having relatively high moisture contents. Provided screen decks are correctly selected, the moist fine material in the incoming ore tends to be removed in the screening stages and therefore does not enter into subsequent crushing units.

All crusher cavities and major ore transfer points should be equipped with a jib-type crane or hydraulic rock tongs to facilitate the removal of chokes. In addition, secondary crushers must be protected from tramp iron by suspended magnets or magnetic head pulleys. The location of these magnets should be such that recycling of magnetic material back into the system is not possible.

Crushing plants for the tonnages indicated may be considered to be standardized. It is not prudent to spend money researching crusher abrasion indices or determining operating kilowatt consumptions for the required particle size reduction in a proposed small crushing plant. Crushing installations usually are operated to produce the required mill tonnage at a specified size distribution under conditions of varying ore hardness by the variation of the number of operating hours per day. It is normal practice to generously size a small crushing plant so that the daily design crushing tonnage can be produced in one, or at most two, operating shifts per working day.

The type of mining relates to hard rock,eluvial, or placer; alluvial deposits. The capital budget you have to invest in buying your equipment with dictate the scale at which you want to mine and influence the long-term operating costs of your mining operation.

Since most of the information online provides lists of gold mining equipment for amateur level mining with equipment like: gold pans, metal detectors, mini sluice box, blue bowl, geologist rock pick, soil scoop, hand screens/classifiers. The items listed just now fall closer to gold prospecting tools and equipment than actual mining.

I will present here what I consider are major equipment lists for 3 types of mining operations. Remember now, a metallurgist is writing. This will not be flawless and since my speciality is process equipment, that is mostly what will be discussed.

Some amateur level gold prospecting equipment such as metal detectors are often classified as mining equipment by small miners/prospectors operating as a hobby. These items include but are not limited to:
