The role of lime before cyanide leaching comes down to three aspects. On the one hand, for the gold concentrate cyanide plant, it is commonly used as a de-agent for the pre-dip grinding classification or thickener. By adjusting the pH value of the pulp, that is, the pH, the anion properties of the flotation reagents (such as collectors and foaming agents) are changed, and they are defeated by competition to achieve the purpose of falling off from the mineral surface. On the other hand, since it is a weak inorganic coagulant, it is used in a pre-dip thickener to eliminate the charge on the surface of the mineral, compress the electric double layer, and form fine aggregates in the slurry to form a clot and accelerate precipitation. Prevent thickeners from running and reduce unnecessary metal loss. Furthermore, by pre-dip alkali leaching (lime CaO leaching) treatment, the concentration of anion and cation in the slurry is adjusted, the leaching reaction conditions are improved, and unfavorable factors are eliminated.

100mm steel rod is usually used as grinding medium in rod mill, while steel ball is used as grinding medium in ball mill.

As regards the second parallelism mentioned, it has been noticed that extremely small amounts of certain colloidal impurities, such as saponine or tannine, were detrimental to flotation, while others, such as Congo red and methyline blue, did not interfere, and were, if anything, beneficial. In classifying these, the injurious ones generally came under the head of what physical chemists call electronegative colloids, while electro-positive colloids were not harmful. This classification is derived from the fact that suspended particles will generally migrate when placed in an electric field, and the classification comes naturally from the direction of their migration. This migration is called electro-phoresis, or electrical endosmose, and is the result of the fact that the liquid containing the particles forms contact-layers around them, similar to the surface-films formed when liquids come in contact with air. These contact-films almost invariably have a difference of potential between their inner and outer surfaces. The film of an air-water contact has, for instance, a difference of 0.055 volts, and other contact-films have similar charges. This causes the particles to act like charged solids, and to be attracted by electric charges of opposite sign.

Copper equivalent (CuEq) calculated using $2.00/lb Cu, $800/oz Au and $12.00/lb Mo and is not adjusted for mining and metallurgical recoveries as these remain uncertain. The formula used is as follows: CuEq = Cu% + (Au g/t x 0.583) + (Mo% x 6).

It is installed with the vacuum ball mill jar, which can grind and test samples in the vacuum condition. It has been widely used in geology and minerals, metallurgy, electronics, building materials, ceramic industry, chemical industry, light industry, pharmacy, cosmetics, environmental protection and other fields.

Fed into the mill through one or both bearing trunnions, the material is ground by impact and friction from the balls. The ground product is discharged from the mill through discharge slots provided in the mill tube, through a discharge wall or through the end trunnion. The design and setting of the discharge slots or discharge wall determine the grain size distribution of the ground product. When performing circuit grinding, the product fineness can be set at the separator. In case of coarse grinding where a downstream screening machine is provided, the product fineness can be preselected by providing a specific mesh width on the screening machine.
