Tailings from inactive uranium mine sites represent a potential secondary source of rare earth elements (REEs). For this study, two tailings (DT and RAT) restored in Ontario, Canada, were used. Bioleaching experiments conducted with mix native sulfur- iron-oxidizing bacteria to test the solubilization REEs, U Th at different temperatures (20, 30 40 °C). The selective recovery REEs bioleaching s...
A native microorganism, Penicillium citrinum was isolated from the top soil of a manganese mine. Based on its efficiency for manganese solubilisation, it was utilized for the leaching of a low-grade manganese ore. The effects of various parameters such as pulp density, particle size, sucrose concentration, inoculum size and bioleaching duration on manganese ore were studied. The optimised condi...
