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 ...

The rock with higher copper content was smelter ore, also called direct shipping ore, and required no treatment before going to the smelter. The rock with less copper was called milling ore, or concentrating ore, and required crushing and separation of ore minerals from the waste rock to produce copper concentrate, which was sent to the smelter.

Ore grade averaged 0.33% Cu s with a copper recovery of approximately 82%. Copper concentrate production in 2013 was 66.2 million pounds containing over 21,000 oz gold and 320,000 oz of silver. 2014 production was 81 million pounds of copper, 22,600 oz gold and 443,700 oz

1976(7), pages 4, 15], The ore body contained both copper oxides and copper sulfides. In the on-site milling operations, a copper precipitate was produced from the oxide ore and a copper concentrate was produced from the sulfide ore. Both were shipped elsewhere for smelting. Byproducts of the milling operation

Copper Mining and Extraction: Sulfide Ores. About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine) These produce many millions of tonnes of copper ore per year The main ores of copper are sulfides and.

Only then are the copper minerals broken free of the rest of the rock to be separated by flotation. Concentrating The slurry of water and pulverized ore is mixed with milk of lime to raise the pH and small amounts of special reagents: a frother to make bubbles, and a collector chemical that causes the copper minerals to stick to those bubbles.
