Concentrate Dehydration process of Lead-zinc Beneficiation Plant in Tibet, Xinhai
La Norma lead zinc mine, located in Kare Town, Chamdo County, Tibet Autonomous Region, is a 600 thousand t/a plant EPC project undertook by Shandong Xinhai Mining Technology & Equipment Inc. The whole plant is composed of four workshops including crushing & screening workshop, grinding workshop, flotation workshop and concentrate dehydration workshop.
In Concentrate Dehydration Workshop, the two- phase mechanization dehydration technological process is used for both lead-antimony concentrate and zinc-sulfur concentrate. The first phase adopts updated high-efficiency thickener for preliminary dehydration. The flotation concentrate is conveyed into thickener by pump. The solid particle suspended in slurry settles down by gravity. The sludge at bottom is continuously scrapped to center discharge port by scraping rake and discharged. The second phase adopts ceramic filter and the water content of final concentrate is 9%.
