|
(a) |
Roasting- presence of oxygen- sulphide ore- oxide ore |
(b) |
Calcinations – presence of oxygen- carbonate ore- oxide ore |
|
(c) |
Froth floatation – presence of blown air- impure sulphide ore- increase concentration of sulphide ore |
(d) |
Smelting- presence of flux- reduction of oxide ore- metal |
