Leaching Mechanism of Aluminum during Column Leaching of Ion-Adsorption Rare Earth Ore Using Magnesium Sulfate
نویسندگان
چکیده
Aluminum is a significant impurity in the ion-adsorption rare earth ore. The changes occurrences of aluminum have great influence on leaching In this paper, column method was employed using magnesium sulfate as agent to investigate effects pH and concentration earths. results show that at low concentrations, earths greatly enhanced, while not significantly affected by decrease agent. At high slight increase observed, accompanied upon decreasing behavior related during process. promotes transition Hy-Al Sol-Al, but due Mg2+ agent, Sol-Al back-adsorbed onto clays transformed into Ex-Al, resulting no content leach solution. However, higher solution comes mainly from transformation Ex-Al. Lowering can promote thereby increasing above provide theoretical support for optimization situ ore sulfate.

Fungal Leaching of Manganese Ore
Bioleaching is technologically feasible for extraction of manganese from low grade ores (containing manganese less than 35% by weight). The principle involves the non-enzymatic reduction of pyrolusite [Mn(IV) oxides] to +2 oxidation state by fungi with the production of metabolites such as oxalic acid and citric acid. In the present investigation, a fungal strain, Penicillium citrinum was isola...
متن کاملOptimization of Acid Leaching of Rare-Earth Elements from Mongolian Apatite-Based Ore
Optimization of the acid leaching process for Mongolian apatite-based ore containing rare-earth elements (REEs) was studied. The ore contained approximately 10% of REEs as total rare earth oxides, and the major impurities were Ca (33% as CaO) and Fe (23% as Fe2O3). Fe bearing minerals could be removed by passing the sample through a wet high-intensity magnetic separator before leaching. After m...
