Copper Mining and Extraction: Oxide Ores

Leaching Oxide Ores with Sulfuric Acid. Copper is stripped from the steel cathode plates when it is thick enough. This cathode copper is 99.99% pure. Solvent Extraction and Electrowinning (SX-EW) production, virtually non-existent before the 1960s, reached nearly 3.8 million tonnes of copper in 2013.

Copper Mining and Processing: Processing of Copper Ores ...

A. Processing of Oxide Ore. Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning.

Heap Leaching Oxide and Sulfide Copper Ores

The acid consumptions curves for the oxide copper ore (number 3) with a high iron oxide-tactile gangue were somewhat different than those of oxide copper-porphery gangue ore number 1. In tests 9 through 14 the incremental acid curves were generally low at the start, fairly high after 3 to 4 days of leaching, and very high thereafter.

Oxide Copper Leach Modeling

The acid leaching of copper oxide ores generates a vertical acid concentration gradient in the ore heap, which is not generally observed in sulfide deposits. Shafer et al have verified Roman’s model and were able to predict the leaching behavior for a relatively large scale column test on coarse ore.

Iron oxide copper gold ore deposits - Wikipedia

Iron oxide copper gold ore deposits. These ore bodies range from around 10 million tonnes of contained ore, to 4,000 million tonnes or more, and have a grade of between 0.2% and 5% copper, with gold contents ranging from 0.1 to >3 grams per tonne (parts per million). These ore bodies tend to express as cone-like,...
