Read More2016-1-1 Gold and silver can be recovered from their ores by a variety of methods, including gravity concentration, flotation, and agitated tank-leaching. Methods similar to heap leaching can be employed: dump leaching and vat leaching (vat leaching is the treatment of sand or crushed ore in bedded vats with rapid solution percolation). Typically, heap ...

The galena was reduced to metallic lead, a process that requires only that crushed ore be sprinkled on a bonfire of stacked wood (3). Sulfur is removed as sulfur dioxide fume, while any silver content dissolves into the metallic lead. Cupellation is the second
Read More2013-11-8 ore by taking advantage of the greater weight mineral compared to the rock. Jigging separates coarse lumps. In this process, the crushed ore is agitated or shaken in water with a vertical motion. This permits the heavy lumps to settle to the bottom and the lighter rock to remain on top. For more finely crushed ore, another concentration method ...

Read MoreFirst ores are crushed and grinded and then gauge or matrix is removed from the powdered ore. This is called concentration of ores. Ores of highly, moderately, and low reactive metals are 1 st concentrated. This step is common for ores of all types of metals. It is carried out by various methods depending upon the nature of the ore.

The big lumps of the ore are brought in between the plates of a crusher forming a jaw. One of the plates of the crusher is stationary while the other moves to and fro and the crushed pieces are collected below (Fig. 18.1).
