Lead and zinc concentrate processing. Processing steps used to produce the lead and zinc concentrates include comminution, flotation, leaching and dewatering. Waste water is pumped to a tailings dam with the flotation overflow. The overflow from the lead concentrate thickener is recycled to the lead flotation circuit.Almost 1% higher zinc grade in the zinc concentrate Much lower lead content in the zinc concentrate (with conventional reagents in the zinc concentrate Pb is 9.89%, while with the SKIK reagent BZ-2000, Pb content is 3.25%) Similar zinc content in the tailings (0.76% 0.77%) with significantly lower zinc content in the feed (0.37%).The most valuable elements in a flotation tailings in Inner Mongolia were lead, zinc and silver, and the main lead and zinc minerals were oxide minerals such as cerussite, sardinianite, smithsonite and hemimorphite, and so on and the content of lead and zinc sulfide minerals such as galena, sphalerite were small. The flotation tailings was used

Oct 14, 2020 Mining takes place underground by long hole open stoping. The extracted ore is then crushed and milled before going through a flotation process to produce zinc and lead concentrates. HZL operates zinc concentrators with combined capacity of about 4 MTPA at Zawar. The tailings slurry generated during beneficiation contains about 40-45% solids ...Furthermore, the leaching concentration of heavy metal lead in tailings treated by 4% Na 2 EDTA increases to 53.44 mg/L which far exceeds the standard of pollution control. Therefore, considering stabilization efficiency and dosage, TMT is the preferred agent for solidifying heavy metals in lead-zinc tailings.
