For this purpose, the type and behavior of molybdenite and copper sulphide minerals during the process by studying the mineralogy of the molybdenite flotation process have been identified. Copper-molybdenum processing complex of Sungun located in East Azerbaijan province, northwest of Iran was selected as a case study. ...

Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode.

Usual multistage grinding and multistage flotation processes are used. (5) Process the smelting slag or intermediate products. For example, in pyrometallurgical copper making, the slag in flash furnace has copper content 1–2%. Mineral processing will render the copper concentrate with copper content 24%, and copper recovery is …

A much more difficult mineral processing challenge is the selective flotation of arsenic-bearing copper minerals (e.g., enargite, Cu 3 AsS 4, and tennantite, (Cu, Fe) 12 As 4 S 13). These minerals have flotation characteristics very similar to non-arsenic-bearing copper minerals (chalcopyrite, chalcocite and bornite).

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.

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.

This is used to make sulfuric acid via the Contact Process. An overall equation for this series of steps is: 2CuFeS2 + 2SiO2 + 4O2 → Cu2S + 2FeSiO3 + 3SO2 (1) (1) 2 C u F e S 2 + 2 S i O 2 + 4 O 2 → C u 2 S + 2 F e S i O 3 + 3 S O 2. The copper (I) sulfide produced is converted to copper with a final blast of air.

This process involves drilling boreholes and pumping a leachate solution - usually sulfuric or hydrochloric acid - into the ore body. The leachate dissolves copper minerals before it is recovered via a second borehole. Further refining using SX-EW or chemical precipitation produces marketable copper cathodes.
