Study on Recovery of Lead Zinc Tailing Ore by

The tailing in a large lead zinc iron sulfur multi metallic mine has rich reservation in variety of metallic minerals. It has been difficult to recover because of all kinds of reasons. The challenges faced by lead zinc ore beneficiation are, low grade and recovery of lead and zinc concentrate for fine disseminated grain size, high oxidation rate and close intergrowth.

Technical Note Cyanide elimination from lead zinc flotation

The process of the lead and zinc flotation concentration is carried out in the base environment and the cyanide is not separated in the gaseous form. However, it precipitates in tailing dumps where it is potentially very dangerous as it can reach surrounding water courses through dams or surrounding rocks (Acic et al., 2001). Since it is much simpler and more economical to solve

Grade prediction of zinc tailings using an encoder decoder

01/10/2021· As the feed of zinc flotation comes from the lead flotation circuit, it is easily influenced by the lead flotation circuit. The zinc grade in the feed of zinc flotation varies between about 5.3% and 10.8%. When the zinc feed changes, some reagents (e.g., CuSO4, 2# oil, Butyl xanthate) should be added to some foam chutes to make tailings grade within the
