  • Purification Of Copper By Electrolysis Metal Extraction

    The metal copper can be easily extracted BUT copperrich ores are becoming scarce so new methods of extracting copper are being developed to exploit low grade ores. A low grade ore is one with low concentrations of copper and research is going on to try and exploit waste material left over from processing high grade ores.The metal copper can be easily extracted BUT copperrich ores are becoming scarce so new methods of extracting copper are being developed to exploit low grade ores. A low grade ore is one with low concentrations of copper and research is going on to try and exploit waste material left over from processing high grade ores.Mining and extracting metal from ores has detrimental effects on the environment and its natural habitats. It is much more energy efficient to recycle metals than it is to extract them as melting and re-moulding requires less energy. Recycling decreases the amount of waste produced, hence saving space at landfill sites and energy in transport.Solvent Extraction and Electrowinning SX-EW production, virtually non-existent before the 1960s, reached nearly 3.8 million tonnes of copper in 2013. Courtesy of ICSG. One of the biggest advantages of using leaching is that low grade ores that would be uneconomic to smelt become economic to leach.The process is more environmentally friendly than traditional extraction methods. Less profit is made from bioleaching which means it is less appealing to buisness men and women. Bioleaching can extract metals from ores that are too poor for other technologies which means less waste. Toxic chemicals are also sometimes produced in this process.
