Mineral processing

There are a number of cells able to be used for the flotation of minerals. these include flotation columns and mechanical flotation cells. The flotation columns are used for finer minerals and they typically have a higher grade and lower recovery of minerals than mechanical flotation cells. The cells in use at the moment can exceed 300 m 3

Bioleaching metal solubilization by microorganisms FEMS

Studies on silicate nickel ores have shown that nickel is dissolved by organic acids produced by microorganisms. The most effective was citric acid. With nickeltolerant strains of Penicillium, up to 80% of the nickel was extracted, depending on the mineralization [19, 63]. Various other valuable metals, e.g., gold, titanium, aluminium
