Copper Mineral | Uses and Properties

Uses of Copper. Native copper was probably one of the early metals worked by ancient people. Nuggets of the metal could be found in streams in a few areas, and its properties allowed it to be easily worked without a required processing step. Copper's metallic luster attracted people's attention. Today most copper is produced from sulfide ores.

A review of copper–arsenic mineral removal from copper concentrates

The common copper–arsenic bearing minerals in copper ores, enargite (Cu 3 AsS 4) and tennantite (Cu 12 As 4 S 13 ), contain significant amounts of copper; 48.4% and 51.6% respectively. Removal of these minerals from the concentrate removes valuable metal, hence income.
