PROCESS FOR RECOVERING COPPER SULPHIDE AND OPTIONALLY MOLD BULDENUM SULPHIDE CONTAINING COPPER BY FOAM FLOATING |
| abstract |
process for recovering copper sulphide and optionally molybdenum sulfide from a foam floatation-containing copper ore process for recovering copper sulphide and optionally molybdenum sulfide from a foam-floatation copper-containing ore, consisting of: - grinding of said ore; - mixing the obtained fine powder with at least one collector and water; - paste aeration; and removing and concentrating the mineral foam formed on the surface of the bath, wherein the collector is a thioglycolic acid derivative having the following formula: r1 is n or o; and R2 is an alkyl group having 2 to 12 carbon atoms. |
