      Manganese leaching; manganese dissolution

    • Abstract


      Manganese can be easily leached from chemically inert manganese ore by aqueous solutions of SO2. Total manganese dissolution occurs at 650 rpm, 0·2% solid, 426µm, pH=1 and 310 K in only 6–8 min. The rate data for managanese fits the equation: 1 − 2/3α − (1 −α)2/3=kt. Diffusion through the siliceous layer appears to be rate-controlling.
