Copper Mining and Extraction: Oxide Ores

This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. A by-product of the smelting and converting furnaces is sulfuric acid. In what looks like a lucky coincidence, sulfuric acid is needed to treat oxide ores in processes called leaching and SX-EW (Solvent Extraction – Electrowinning). The acid ...

copper extraction and purification - chemguide

Extracting copper from other ores. Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution. Concentration of the copper(II) sulphate solution by solvent extraction. The very dilute ...

Copper Mining and Processing: Processing Copper Ores ...

The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different chemistries of the ore. Copper oxides are more abundant near the surface, but are considered low-grade ore, with a lower concentration of copper. Although this requires more ore to be extracted and processed, this

Copper Concentrates - Cargo Handbook - the world's

The beginning for all copper is to mine sulfide and oxide ores through digging or blasting and then crushing it to walnut-sized pieces. Crushed ore is ball or rod-milled in large, rotating, cylindrical machines until it becomes a powder usually containing less than 1 percent copper. Sulfide ores are moved to a concentrating stage, while oxide ores are routed to leaching tanks. The first ...

Copper Oxide Flotation - Mineral Processing Metallurgy

16/04/2018  Oxide copper minerals generally do not respond well to traditional methods of concentration using known sulfide copper collectors. Their recovery in a froth flotation circuit requires special treatment.
