Heap leaching -

Heap leaching is an industrial mining used to extract precious metals, , uranium, and other compounds from using a series of chemical reactions that absorb specific minerals and re- them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places on a liner, then adds the chemicals via drip systems to the ...

    In the flotation process, the finely ground ore, mixed with water and special reagents, is agitated by mechanical and pneumatic devices. These produce air bubbles in the ore-water mixture, or slurry. The reagents provide an attraction between the surface of the copper minerals and the air bubbles.

    Copper extraction -

    Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated concentrated. The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals such as chalcopyrite, th…
