Copper Mining and Processing: Processing Copper Ores

A. Processing of Oxide OreB. Processing of Sulfide OreC. Recycling CopperOxide 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 Leachingis the process of using percolatin在superfund.arizona.edu上查看更多信息

Innovations: Introduction to Copper: Mining & Extraction

Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and isاحصل على السعر
