The leaching methods mainly include heap leaching, underground leaching, agitation leaching and bioleaching. Heap leaching method is widely used in the treatment of copper ore, tailings and ore without breaking or crushing. In the leaching percolation tank or pool, it is suitable for treatment of high grade concentrate or < 5mm and the particle size of ore; leaching is usually used for processing ore or concentrate, high metal recovery rate, leaching speed. The leaching solvent extraction electrowinning method not only can offer high quality of cathode copper from ore at the mine site, and the initial investment and production costs were compared with the conventional pyrometallurgical processing and low leaching in North and South America spread rapidly, currently in the country has also been widely used. Mine stone the process of general requirements to meet the conditions: (1) the main copper minerals in the ore is easily the best leaching of chalcocite; (2) can not consider the recovery of gold and silver, molybdenum and other by-products; (3) the gangue mineral acid consumption must be within the allowable range; (4) low temperature and rainy, higher altitude meteorological and geological conditions are not conducive to heap leaching; (5) can make full use of existing equipment to reduce new investment; (6) concentrate the management problems of supply and demand. The main advantages of this process include: processing of copper ore grade is low, especially suitable for processing low-grade ores, waste and low-grade and difficult mining and refractory refractory ore, and has the advantages of simple process, low cost, low energy consumption, little environmental pollution and other advantages, the United States has begun to use the process of low grade copper ore grade is lower than 0.04% the process is simple, low energy consumption, low cost, investment cost, short construction period, no environmental pollution, the production process of cathode copper is.
Rod mills (see Fig. 17) follow the general dimensions of tube mills with diameters from 3 to 6 ft. and lengths from two to three times their diameter. They differ from ball mills in that steel rods 3 or 4 in. shorter than the mill length inside the liners are used as grinding media. Rod mills are often run on tires and rollers instead of trunnions or on one trunnion and one tire and set of rollers.
The depressant compositions are compatible with various other flotation reagents known to those skilled in the art including, for example, frothers, modifiers, dispersants, pH regulators, surface modifying agents, activators, collectors, stabilizers, depressants, or any combination of two or more of these reagents. Accordingly, any or all of the embodiments of the depressant composition disclosed herein can include any one or more of such flotation reagents.
The magnetic field of ZCTS (N.B) series of permanent magnet drum magnetic separator has two kinds of structures: rotating and fixed. The fixed is suitable for wet sorting of fine particles of strongly magnetic material in weak magnetic fields, or removing the non-magnetic minerals in the strong magnetic minerals. When the slurry is injected into the magnetic field, the strong magnetic mineral is adsorbed on the cylinder surface, the weak magnetic and non-magnetic minerals are successively excluded, the strong magnetic minerals adsorbed on the cylinder was taken out of the magnetic field with the rotation of the cylinder. The rotating one is suitable for dry sorting of fine strong magnetic minerals, for the role of high-speed rotation, the amount of rolling of the magnetic particles in Wet magnetic separator is much larger than the ordinary magnetic separator. It has a significant the effect for the destruction of magnetic agglomeration and improves the high-grade ore. There are two kinds of sorted materials: magnetic material and non-magnetic material, the machine is suitable for roughing and selecting materials whose sizes are 6-0mm.
The material between the rolls is submitted to a very high pressure ranging from 100 to 200MPa. Special hard materials are used as protection against wear, for example, Ni-hard linings to protect the rollers. During the process, cracks are formed in the particle, and fine particles are generated. Material is fed into the gap between the rolls, and the crushed material leaves as a compacted cake. The energy consumption is 2.5–3.5kWh/t and about 10kWh/t when recycling of the material is used. The comminution efficiency of a HPGR is better than ball mills such that it consumes 30–50 % of the specific energy as compared to a ball mill. Four circuit configurations of HPGR can be used in grinding of raw materials, clinker and slag such as :Pre-grinding unit upstream of a ball millHybrid grindingSemifinish grindingFinish grinding in closed-circuit operation.
(3) Without raw material on the grinding table, the mill can run, which erases the difficulty in starting.
In some cases a chemical reaction between the solid and the reagent occurs at the interface ; for instance, in the activation of sphalerite by copper sulphate a film of copper sulphide is deposited on the mineral following adsorption of the copper salt at its surface. In many cases there is no evidence of any chemical change, but, whether chemical action takes place or not, there is no doubt that the filming of the mineral is due primarily to the adsorption property of the liquid itself, by virtue of which the promoting reagent dissolved or suspended in it is concentrated at the interface.

I grind about 65 pounds of wheat every week using my Country Living mills.I have two of them mounted on a bicycle.It takes less than three hours--I do about an hour of grinding at a time and have a table my husband made so I can read while I grind.I use the flour to make bread in my brick oven for my local bakery.The Country Living mills work great.I vary the grind depending on what I'm making.I use the plexiglass hopper extenders so I don't have to get off the bike and refill as often.The mill is attractive and the company is very responsive to questions and comments.
We discovered that uranium occurs in many rare earth minerals and that these elements need to be removed before the individual rare earth elements could be separated. Of course, uranium recovery is our main business. We began internal laboratory testing on a number of rare earth mineral samples and got very positive results.
