A few tons of copper ore for assay, mill tests, and similar purposes have been brought out from the Kotsina-Kuskulana district, but no shipments of commercial ore have been made. Probably no large shipments will be possible in the near future, for none of the copper properties are equipped for mining and handling ore in a commer­

What are the important ores of copper?

Copper is only about 0.005% of the earth''s crust, but it occurs in a large number of common mineral species (pyrite, chalcopyrite, malachite, azurite, etc.). Many of these minerals are found in common types of ore-forming deposits, wide-spread aro...

Oxidation Roasting of Fine-Grained Carbonaceous Gold Ore ...

The oxidation roasting of carbon-bearing micro-fine gold can eliminate or weaken the robbing effect of carbonaceous materials and clay, and destroy the encapsulation of micro-fine gold. The micropores produced by gas escaping during the roasting process are conducive to the diffusion of leaching agents, thus enhancing the cyanide leaching of gold.

Tailings

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water ...

Grain size is highly variable and is generally controlled by primary sulfide mineralogy and the extent of metamorphic recrystallization. Primary sulfide minerals of most zinc-lead-copper deposits are fine grained and intergrown, whereas those of most copper-zinc deposits are coarser grained (Franklin, 1993). The extent of grain size changes
