Weight loss of the leach residue was 34.0%, with relative copper content increased by 1.0%, zinc content decreased by 6.18%, and iron content decreased by 15.1%. Biooxidation of ferrous iron in the pregnant leach solution by three microbial cultures was also studied. The most effective culture was moderate thermophilic

Jul 12, 2021 One of the development trends of mining is the application of bioleaching technology to recover important metals from various low-grade ores. Compared with traditional mineral processing technology, biological leaching technology has the characteristics of low cost, easy operation and low pollution. Leaching bacteria of copper beneficiation

Unlike sulfide ore, the beneficiation of oxide ore involves acid leaching, where the copper is liberated by the addition of sulfuric acid. The liquor, commonly known as PLS (pregnant leach solution), is an acidic, metal-laden liquid that needs to be clarified – or beneficiated – to separate the leached copper

W.G. Davenport, in Encyclopedia of Materials: Science and Technology, 2001 1.1 Physical Beneficiation. Beneficiation of copper ores is done almost exclusively by selective froth flotation. Flotation entails first attaching fine copper mineral particles to bubbles rising through an ore–water pulp and, second, collecting the copper minerals at the top of the pulp as a briefly stable mineral
