Cobalt extractionA feed of matte and sulfide concentrate containing approximately % cobalt and 30% sulfur is pressure leached at elevated temperature and pressure in an ammoniacal solution to produce a solution of nickel, copper and cobalt. By boiling away the ammonia; copper is precipitated as a sulfide and sent to a smelter.
Concentration of OresThe first step is to heat the bauxite ore to temperatures of 200°c along with a sodium hydroxide solution. This will convert the aluminium oxide to a solution of sodium aluminate. The silica will dissolve itself in the process. The chemical equation is. Al 2 O 3 + 2 NaOH → 2 NaAlO 2 + H 2 O.
