— The gravity method offered a sulphur recovery of about 84 wt%. The pyroanalysis of gold (Au) and silver (Ag) on the concentrate of desulphurisation with gravity methods display a gold content of 3,78 g/t and of 4,9 g/t for silver. The precious metals recovery could offset partially the costs related to the waste handling and reprocessing.
