Solution
The correct option is B roasting
Froth flotation process is used for concentration of sulphide ores. Furthermore these concentrated sulphide ores are converted to its oxide form by roasting them. During roasting, the sulphide is converted to an oxide, by heating them in the presence of oxygen or air, at a temperature lower than its melting point.
