Heap leaching Wikipedia

This method is an acid heap leaching method like that of the copper method in that it utilises sulfuric acid instead of cyanide solution to dissolve the target minerals from crushed ore. The amount of sulfuric acid required is much higher than for copper ores, as high as 1,000 kg of acid per tonne of ore, but 500 kg is more common.

Therefore, we proposed an equipment standard for the primary copper smelter NESHAP that would require that the process off-gases from smelting furnaces, slag cleaning vessels, and batch copper converters be discharged through a by-product sulfuric acid plant (or other type of sulfur recovery process unit that requires comparable levels of gas

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).

Copper Smelting and Refining Process Pan Pacific Copper

After electrostatic precipitators remove dust particles in the gases, the gas is transferred to the sulfuric acid plant. At the sulfuric acid plant, the catalytic reaction of vanadium oxides causes SO 2 to oxidize into SO 3, which is absorbed in water to yield concentrated sulfuric acid. The manufactured concentrated sulfuric acid and oleum is

Copper Mining and Extraction: Oxide Ores

Crushed ore in the leach pad. The pregnant leach pond is in the distance. The crushed ore rests on a leak-proof membrane to protect the underlying ground and prevent the acid and copper ions polluting the local water table. 2. Dilute sulfuric acid is poured over the crushed ore using an irrigation system. (Courtesy of Red Tiger Mining Inc.)
