OverviewConcentration (beneficiation)HistoryRoastingRefiningConcentrate and copper marketingSee alsoBibliography

The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals being less than 2% of the total volume of the ore rock. Thus, all mining operations, the ore must usually be beneficiated (concentrated). The concentrate is typically sold to distant smelters, although some large mines have smelters located nearby. Such colocation of

Copper extraction Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper ores consists of a series of physical, chemical and electrochemical processes. Lime is used to raise the pH of the water bath, causing the collector to bond more efficiently to the copper sulfides. The process can produce a concentrates

Innovations: Brief Early History of Brass Copper

The vapor from the zinc permeated the copper to form brass, which could then be melted to give a uniform alloy. Only in the last millennium has brass been appreciated as an engineering alloy. Initially, bronze was easier to make using native copper and tin and was ideal for the manufacture of utensils.
