Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
Recently, copper-citrate-thiosulfate leaching was tested on refractory gold ore, exhibiting a similar extraction capability for gold, in which the predominant gold species is Au (S 2 O 3) 2 3 − rather than Au (N H 3) 2 + (Wang et al., 2019).

Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated before refining (e.g., via ...
Copper ore powder flotation machine can guarantee better stability index for refractory and complex copper ore or high-grade concentrate. In the flotation process, the equipment parts wear less, the energy …

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
