Study on flotation column separation of pyrite from a lead zinc mine

The reformed ore body is a famous lead-zinc sulfide deposit in China. The sulfur content of the ore body is higher than 30%. In recent years, China has paid more and more attention to environmental protection. A large number of sulfuric acid plants have been closed down, and the price of sulfur has plummeted. Therefore, the management has paid attention to the fine management of sulfur selection.

By using flotation column as sulfur flotation equipment, the whole process of automatic operation, maintenance cost and use cost decreased by 30%, flotation recovery rate increased by 2%, and economic benefits were remarkable. At present, the system has been running smoothly for 6 years.
