Copper Ore Processing Methods

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 ...

Copper is extracted from the solution to create pure copper sheets; Mining solution is recycled back to the well field; Once an area is mined, the wells are flushed with water to clean out any remaining leaching solution. Meanwhile, the surface is returned back to pre-mining conditions, allowing it to be used for any purpose in the future.

“The initial capital investment in the use of the mining system is high, but the operating cost is low which makes this mining system attractive,” he says. After companies take the initial investment leap, the cost of block caving itself could work at about one-tenth of the corresponding cost of conventional mining methods, with production rates reaching 30,000 to 100,000 tons per day with no backfilling costs.

Copper Mining and Production Processes Explained

Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning).

Copper Smelting Process - Furnaces Used, By

Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity. Copper can be recycled indefinitely without the base metal being compromised ...
