Experimental Study on Flotation Separation of a Lead-zinc Sulfide Ore
In order to efficiently and comprehensively recover and utilize the lead-zinc sulfide resourc-es in a certain place,in view of the slightly complex characteristics of the mineral composition of the ore and the dissemination relationship of useful minerals,under the condition of grinding fineness of-0.074 mm 85%,the flotation process of preferential lead separation-lead tailings re-concentration zinc is adopted.Fi-nally,lead concentrate with lead grade of 63.052%,lead recovery of 93.56%,zinc grade of 8.347%,zinc re-covery of 5.30%and zinc concentrate with zinc grade of 46.352%,zinc recovery of 88.85%,lead grade of 0.794%,lead recovery of 3.56%are obtained.Both lead and zinc have achieved good recovery and utiliza-tion.
