A copper ore from the Okiep Copper Company in the Okiep area of the Northern Cape province of South Africa was used in all tests. Its average copper grade was 1.8% and mineralogy showed that the main copper sulphide was bornite (Table I). Other copper sulphides noted were chalcocite, chalcopyrite, digenite and possibly enargite. Pyrite was the
