    The reported list of toxic Cu species (Sorenson, 1991) often includes Cu(OH) +, Cu 2 (OH) 2 2+ and CuCO 3. However, without doubt, Cu 2+ ions that are present in various aqueous solutions (their presence is a function of pH) are considered to be the most toxic of dissolved copper species (Freematle, 1989 Khalifa et al., 2001 Sorenson, 1991).The ore is crushed, ground and then enriched (concentrated) by Froth Flotation. The powdered ore is mixed with a special paraffin oil which makes the copper mineral particles water repellent. It is then fed into a bath of water containing a foaming agent which produces a kind of bubble bath.
