Tank leaching - Wikipedia

Tank vs. vat leaching Factors. Tank leaching is usually differentiated from vat leaching on the following factors: In tank leaching the material is ground sufficiently fine to form a slurry or pulp, which can flow under gravity or when pumped. In vat leaching typically a coarser material is placed in the vat for leaching, this reduces the cost of size reduction;

Copper passes from the aqueous leach liquor phase to the organic phase in the extraction section and back from the organic to the aqueous electrowinning plant feed in the stripping section. LIX 64N solution comes into contact first of all with the aqueous solution most depleted in copper and therefore having a higher ferric iron/copper ratio ...

Copper extraction - Wikipedia

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).
