The World’s Top 10 Highest Grade Copper Mines

Nov 25, 2019 The world's 20 largest copper mines produce nearly 9 million metric tons of the precious metal a year, about 40 of the world's total copper mine capacity. Chile and Peru, alone, account for than half of the copper mines on this list. The U.S. makes the cut, as well, with two mines among the top 20. Copper is expensive to mine and refine.

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.

This reduction in lime is equivalent to approximately $700,000 per annum at current production rates.CITATION Kirkwood, B, Kinal, J, Siliezar, J and Sofatzis, H, 2013. Low pH trial in the Ernest Henry Mining copper rougher flotation circuit, in Proceedings MetPlant 2013 , pp 371-377 (The Australasian Institute of Mining and Metallurgy Melbourne).

A new reagent system, developed by Versitech, Inc., with assistance from DOE's Inventions and Innovation Program, recovers copper minerals at a much lower pH than conventional reagents and avoids floating pyrite. The process reduces or even eliminates both the lime used in copper flotation and the accompanying carbon dioxide.

And chemical properties of small copper ore particles. To maximize the yield of copper, pH control is necessary in the flotation tanks. Crushed ore (containing 1 to 2 copper), along with water and a lime slurry, is fed into a ball mill. This rotating drum contains steel balls that further crush the ore to a fine powder. When the ore lime.
