Comprehensive Utilization Of Cyanide Residue Of Lead And Zinc Ore Dressing Wastewater Containing Cyanide,

The gold tailings in tailings storerooms are some mixture of waste water and Solid slag during the gold produetion. They are wasteful of precious mineral resources and occupy a large of lands. At the same time,they have bad effect on the production enviromnent.In this paper, the cyaniding tailings was used for experimental material and the circulation of water was used for expetimental water.we make a detailed study of the lead-zinc mixed flotation.According to the expererinental rusults of the water flotation and the circulation of water flotation. The results indicate that the circulation of water need to be pretreatmented. As experimental watter in the circulation of water pretreatmented, We studied the lead and zinc mixed flotation as circulation of water pretreatmented. It can be seen that the lead concentrate of high quality is produced; assaying about 40.06% Pb,and the flotation recovery of lead is 43.65%,and the zinc concentrata of high quality is produced; assaying about 17.53% Zn, and the flotation of zinc is 33.93%. Under the circulation of water pretreatmented condition, The lead grade and recovery has close to the closed flowsheet with water,there are greater the application and development prospects value.
