Manganese Extraction Process Of Aluminium

Aluminium atoms easily bind with other metals, forming compounds. At the same time its impossible to isolate aluminium by simply melting down the compounds in a furnace, as is the case with iron, for example. The aluminium production process is much more complex and

  • A New Process for Cobalt Nickel Separation

    A New Process for Co-Ni Separation ALTA 2010 5 a high NiCo ratio, sufficient to satisfy cobalt purity requirements for LME Grade Nickel. This extraction is achieved using a synergistic mixture of Versatic 10 and LIX 63. There are two basic steps involved, as in any solvent extraction process extraction and stripping.


    The cathodic hydroxide OH ion can cause manganese hydroxide precipitation on the cathode surface which is prevented by pH buffer ammonium sulphate and proper concentration of MnCO3 in the Catholyte . H2SO4 generated in the process is recycled to dissolve MnCO3. Electrowinning of Mn metal proceeds at about 60-70 of current efficiency ...
