Description
Lead-zinc beneficiation plant
Lead zinc ore is processed mainly through flotation method,
according to the nature of the ore, mixed flotation and preferred
flotation can be used, specific process should be determined
through the beneficiation test index.
Application
The lead-zinc ore dressing process mainly deals with lead zinc
sulfide ores with close intergrowth, uneasy dissociation and uneven
particle size distribution.
Beneficiation process
1. Preferred flotation
After the ore grinding to the monomer dissociation of lead-zinc,
lead and zinc will be separated respectively. It is suitable for
coarse grinding fineness adopting single grinding classification
process, different concentrates are separated by flotation reagents
combination.
2. Mixed flotation
After grinding the raw ore, mixed flotation will separate the zinc
and lead together and then re separate zinc concentrate from lead
concentrate. It is suitable for strong associated lead-zinc ore,
when necessary to regrind concentrate thus better separation of
lead and zinc concentrate will be made.
