Leaching of Mt Weld Phosphate Ores with Acetone-water-SO2 Mixtures
The effect of leaching three samples of Mt Weld ore with a-hydroxysulphonic acid [(CH3)2(COH)SO3H] was assessed. Apatite present in the samples was found to be readily soluble but calcination up to 600C was required to increase the solubility of crandallite. Increasing the calcination temperature increased dissolution of both phosphate and alumuuum. The optimum SO2 content in solution for the dissolution of crandallite ores was found to be lower than for apatite.
