2020-2-20 · The flow of lead and zinc priority froth flotation process is mainly to suppress zinc first and float lead, then activate zinc to get lead concentrate and zinc concentrate. According to the buoyancy degree of lead zinc ore, the valuable minerals, such as lead and zinc, can be recovered successively by the froth flotation process.

The Depression of Sphalerite during Carbon Pre-flotation ...

2017-2-20 · of sphalerite as composite particles during lead flotation, and (c) the pulp pH was best maintained at natural pH during pre-flotation and at an elevated alkaline pH (pH 9.5) during lead flotation for optimal selectivity. In terms of depressants it was found that zinc sulfate specifically depressed sphalerite during lead flotation.
