The largest source of copper is from porphyry ore deposits in which one or a combination of the aforementioned minerals occurs. A typical copper sulphide ore contains various levels of iron sulphide types that generally include pyrite (FeS2) and pyrrhotite (Fe1-xS). Often gold and silver are present which may either be associated with the sulphides or are free. The gangue particles can consist of a range

2.7.4.1.2 Copper Ore Leaching by Ore Type. The leaching of copper ores is conducted somewhat differently depending on the minerals present in the ore. Oxide ores containing chrysocolla, malachite, azurite, cuprite, etc., are readily amenable to acid leaching. An acid solution is often mixed with the ore during agglomeration to initial leaching while the material is being stacked. After stacking, the heap is

Copper is found as native metal and in the minerals cuprite, malachite, azurite, chalcopyrite and bornite. It is also often a by-product of silver production. Sulfides, oxides and carbonates are the most important ores. Copper and copper alloys are some of the most versatile engineering materials available. The combination of physical properties such as strength, conductivity, corrosion resistance, machinability and ductility make copper

More About Standard Types of Copper Ores: In some deposits the oxidized ores and in some the primary sulfide ores are rich enough to work. Yet in other deposits, only the enriched ores of the secondary sulfide zone are profitable. In the oxidized zones of sulfide deposits the mineral waters are sulfuric acid and ferric sulfate solutions. Such solutions dissolve copper readily, and in contact

Ore Wikipedia

Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. The grade of ore refers to the concentration of the desired material it contains.
