Copper minerals can be broadly classified into sulfide minerals, oxide minerals, and native copper. The most common copper mineral is chalcopyrite, a sulfide mineral that contains about 34% copper by weight.Other important copper minerals include bornite, chalcocite, and malachite.These minerals can occur in a wide range of …

Cu oxide refers to either cupric oxide (CuO) (80% Cu) or cuprous oxide (Cu 2 O) (89% Cu), both of which exist in nature (Aoyagi and Baker 1993). Due to high Cu% in Cu oxides, smaller amounts of them are used in broiler chicks feed compared to this of CuSO 4 -5H2O (25% Cu) (Baker et al. 1991 ).
