Lead & zinc are always symbiotic, and flotation is mostly used for lead & zinc beneficiation. Prominer has rich experience in providing the technological solution for lead &zinc ore to achieve high recovery rate and yield.
For the flotation of lead and zinc, there are several differences according to the characteristics of the raw ore. General processing technologies for copper ore are summarized as below:
I. Physical processing technology:
Crushing & grinding solution
Flotation process is mostly used for lead and zinc beneficiation. The ore pulp slurry is pumped to flotation cells for extracting. The flotation cells are divided into several parts: roughing, concentration and scavenging (the exact numbers of stages for each part should be decided by test work to reach the best recovery), and with the use of frothing agent and collecting agent, the lean & zinc concentrate will be collected. Sometimes the lead will first be separated and then zinc; sometimes lead & zinc will be concentrated together and then after reagents removing the lead and zinc can be separated. Normally there are one stage separation or multi stages separation for the technological process.
