Pb-Zn ore dressing process

1、Priority flotation process , according to the different floatability and different float speed , recover the plumbum concentrate , zinc concentrate and sulfide concentrate  by sequence . This process could reduce the capacity of flotation tank ,economize reagent .

2、Mix-separating flotation process --- this process is to mix all the sulfide zinc and sulfide plumbum into the mixing concentrate , abandon tailings . This process is more effective in separating plumbum and zinc .

The flowsheet as below :

3、Asynchronous flotation ---normally different minerals have different floatability , asynchronous flotation is to separate plumbum and zinc in different steps to ensure the most effective floatability of minerals in a suitable condition .
