The ore is a sulphide ore and it can be concentrated by roasting. Roasting is a process in metallurgy in which a sulphide ore is heated in high temperature in air. The process may convert a metal sulphide to a metal oxide . Example: Roasting ZnS may yield ZnO.

The metal can be obtained from the ore by magnetic separation.
