Wolframite Slime Recovery – Selective Flocculation Flotation Method

Wolframite slime is an beneficiation issue due o its fine particle. It is ever harder to recycle finer minerals in slime. In recent years, to deal with fine particle wolframite slime effectively, there is a method to accumulate first and beneficiation second, selective flocculation flotation method is one of the newly developed wolframite slime recycle method.

The applied flocculation agent is polyacrylic acid, after years’ application, use polyacrylic acid and sodium oleate together to improve floating standard of fine concentrate, it is called CPC flocculation flotation. When pH value is 6.8, for concentrate particle smaller than 20um, and separate by quartz artificial mixed mine, can obtain concentrate with grade 69%, recovery rate 91%. Compared to regular flotation method, it improves 17.83%. Flotation efficiency reaches 69.1%.

Selective flocculation method is simple in wolframite slime recovery process, it is easy for industrial production and has wide application field for concentrate minerals recycle.
