Bauxite ore processing Plant

2015-7-14 · Bayer process is the main industrial method in alumina producing. Bayer process is suitable for processing low silicon bauxite with good quality but is not suitable for goethite with aluminum. The production process is that: in the pressure cooking device, caustic alkali is used to leach bauxite so that we can get sodium aluminate solution.Biomining: metal recovery from ores with microorganismsBiomining is an increasingly applied biotechnological procedure for processing of ores in the mining industry (biohydrometallurgy). Nowadays the production of copper from low-grade ores is the most important industrial application and a significant part of world copper production already originates from heap or dump/stockpile bioleaching.
