Purifying and reusing flotation wastewater of sulfide mine is one of great study tasks which national non-ferrous metal mine must be faced with.

In order to solve serious pollution of flotation wastewater in our country, a new technology is developed, which is described as coagulation precipitation -activated carbon adsorption-wastewater reusing.

This subject is launched to resolve the questions of large quantity of sludge, difficulty of Solid-Liquid Separation and no reutilization in the application of mineral in the treatment of nonferrous metals flotation wastewater.
