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.
Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0 percent copper. The refining techniques employed by copper producers depend on the ore type, as well as other economic and environmental factors. Currently, about 80 percent of global copper production is extracted from sulfide sources.
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger ...
Sep 26, 2019· Virtually all sulfide-type copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) and covellite (CuS), are treated by smelting. After crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic.

Apr 23, 2011· Both ore types can be economically mined, however, the most common source of copper ore is the sulfide ore mineral chalcopyrite, which accounts for about 50 percent of copper production.
The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example: FeO(s) + SiO 2 (s)→ FeO.SiO 2 (slag) This is .
The metals in ore can occur in many different minerals (compounds) in the rock. As an example, copper occurs in more than 50 minerals with varying percentages of copper in the chemical formulas of those minerals. The richest grade of copper ore is native copper, which is pure copper (). Many metallic ores occur as sulfide minerals.
