Froth flotation - Wikipedia

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.

How to Remove Fluorine from Copper Concentrates

The presence of fluorine in copper concentrates is usually harmful to sulfuric acid plants attached to copper smelters (Beer, 1992). Fluorine can deteriorate acid proof tiles, fiberglass pipes, packing and catalyser substrate which contains SiO2. It can also damage, to a less extent, cast iron pipes.

SRU Sulphur Recovery Process - Mineral Processing & Metallurgy

Ordinary lump sulphur should have a guaranteed sulphur content of 99.5 per cent and be practically free of arsenic, selenium, lead, copper, zinc, iron, and moisture. Production Problems Flotation concentration of crude native sulphur does not usually produce a finished grade of sulphur but does make a much higher recovery than treatment by autoclave.
