Oil substances and galena,marcasite,and pyrite with better flotability in ore can form flocculant,the flocculant is tight and not easy to disperse,so it will affect the grade of lead concentration.The joint mechanism of"dispersion+reagent removal"was adopted for selection.2# oil was adopted for separation of lead rough concentration;sodium silicate was adopted for lead rough concentration as a dispersant,the activated carbon powder was adopted for reagent removal,lime was adopted for inhibition of easy-to-floated marcasite and pyrite;a small quantity of diethyldithiocarbamate was adopted for collecting,to production of qualified lead concentration products.When a lead grade is 0.87％,and zinc grade is 5.40％contained in the ore,it can obtain qualified concentration that lead concentration with Pb 55.20％,Zn 4.14％,and the recovery rate of lead is 89.83％,it can realize available recycling utilization of lead metal.
