Copper/gold ores that require uneconomically high quantities of cyanide to process due to the solubility of copper in cyanide. A multitude of other unfavorable constituents including pyrrhotite, tellurides, antimony, and arsenic. It should be noted that most of the refractory ore treatment processes are
Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.
Copper, uranium, vanadium and other metals are produced by solvent extraction. The figure below is a simplified schematic of a typical copper solvent extraction process. Oxide copper ore, lowgrade copper sulfide overburden, and other coppercontaining materials are stacked into a heap.

Some gold can be found by panning in rivers; heavy gold will remain in the pan, whereas lighter rocks and minerals float out. This smallscale form of gold mining has little effect on the body of water, but the largescale practice of mining gold from ore can have tremendous negative effects on water quality.
