Laboratory-scale sulphation roasting testwork for copper .

Cobalt generally does not form the oxy-sulphate intermediate product. Cobalt sulphate, copper sulphate, and copper oxy-sulphates are generally soluble in mild leaching conditions. In the overall sulphation process, some excess oxygen is required in order to shift the reactions towards the formation of the metal sulphates and oxy-sulphates.
