(1) Lead flotation need to put a large number of lime, the subsequent selection of zinc need to add a lot of Ammonium Bicarbonate to adjust the pH value, which cause high ammonia content, working environment bad;
(2) High alkali environment lead to zinc oxide flotation bubble rich and large viscosity, high pH backwater, need to be treated before reuse;
(3) The original desliming flotation process resulted in nearly 50% loss of zinc metal and low recovery of zinc oxide.
(1) Low alkali and desliming process adopted. During lead flotation process, use combination of collector which has better effect for lead selection, improve the efficiency of lead flotation;
(2) develop and use one kind of zinc oxide flotation miscible collector, zinc oxide mineral flotation recovery significantly improved.
(3) When the original ore containing zinc 7%, lead 0.7%, the final zinc sulfate concentrate containing 54% lead, lead 1.2%, zinc recovery rate of 70%, zinc oxide concentrate 35% zinc, lead 4.3%, zinc recovery Rate of 14%, total zinc concentrate 50%, the total recovery rate 84%, to achieve the efficient comprehensive recovery of hard selection lead-zinc mine;
(4) Industrial test to improve lead recovery rate of 4%, reduce the cost of flotation agent RMB 6 yuan / ton.
