| The flotation separation of copper sulphides ore containing gold is affected by soime factors,such as grinding fineness,collectors,modifiers,etc.The author worked out the selective flotation flowsheet in accordance with different flotation characteristics of various minerals.The flotation separation of copper,gold and sulphur minerals was successfully done under appropriate condition.Better results have been obtained,Accor-ding to the difference of flotability of copper and sulpliur minerals,cop-per and sulphur flotation separation was successfully achieved by using the combined CP depressant and lime.A higher quality copper concentrate was obtained.The flctation results were better than the plant production indi-ces.The technology solved the difficuIt problem to be sold by reason of low grade of Copper concentrate in concentrator. |
