Creative process, low operation cost. Cu-Pb mixed concentrate regrinding process saves the grinding cost without fine grinding all the ores are, and it makes further monomer dissociation to create favorable conditions for the separation of copper and lead. [Cases] Case 1. Tibet Lead zinc Beatification Plant is one of our successful cases.

After the raw ore was ground to -0.074mm (90%), copper concentrates were produced through the flotation process of one-stage roughing, three-stage scavenging and four-stage concentration. The concentrates had a Cu grade of 20.23%, a Cu recovery of 74.35%, an Au grade of 4.41g/t, an Au recovery of 75.66%, an Ag grade of 3,526.63g/t and an Ag ...

It can be seen that, Pb accumulation was the highest in phylloplane, followed by Zn, Cd, and Cu. HM contents in most samples surrounding the pollution source showed a general increase compared to the samples from the sites far away from the pollution source (CK-1 and CK-2), especially that of Cd, Pb, and Zn.
