Calcination or Roasting of Ores

The object of calcining or roasting certain ores before treatment is to dissipate the sulphur or sulphides of arsenic, antimony, lead, etc, which are inimical to treatment, whether by ordinary mercuric amalgamation or lixiviation The effect of the roasting is first to sublimate and drive off as fumes the sulphur and a proportion of the objectionable metals What is left is either iron oxide ....
