Froth flotation Froth flotation

Froth flotation

Froth flotation is a process for selectively separating hydrophobic materials from is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Pyrite Depression Pyrite Depression

Pyrite Depression

Pyrite floats at very low pH or gets entrapped during flotation. Column flotation will give good results for such problems. It has forth washing system where entrapped minerals are separated, to get very clean concentrate. 4 years of RD in RDM proved to reduce silica from 7 to 3% in Zinc cleaning in column with very low pyrite.
