Review of the Impact on Water Quality and Treatment

Mar 15, 2016 The gold recovered from crude undergoes refining to produce crude bullion containing between 90 and 99.5% pure gold . Refining involves roasting the crude gold to convert base metals such as iron, lead, copper and zinc to their respective oxides. This process is then followed by smelting, which removes base oxide impurities in form of slag.
