  • Roasting of mixed sulphide ores or concentrates
    Patent number: 4478794
    Abstract: In the roasting (oxidation) of mixed zinc sulphide/lead sulphide concentrates, to give an oxidic product for reduction, improved sulphur elimination and reduced lead volatilization are achieved by mixing 2-20% by weight of zinc oxide with the mixed sulphide materials, forming pellets of 2-15 mm diameter and roasting these under controlled oxidation conditions, firstly at a lower temperature and then at a higher temperature; preferably at 850.degree.-950.degree. C. for the first stage and at 950.degree.-1050.degree. C. for the last stage.
