The pH range of feldspar in the cationic harvesting system (pH=4-11) is smaller than mica, so mica can be preferred to separate under the strong acid conditions. 02 02. Flotation separation of feldspar and silica sand. The feldspar and silica sand belong to frame silicate minerals.

Stability and flotation behaviour of silica in the ...

This present work deals with the stability and flotation efficiency of silica in the presence of a cationic surfactant, dodecylamine (DDA) and a non-polar oil, dodecane. Dispersion stability was defined by turbidity measures and the flotation tests were carried out in a laboratory scale flotation cell.

Flotation Collectors - Mineral Processing & Metallurgy

Flotation Collectors. Simply said; a Flotation Collectors is a chemical used to make the surface of minerals, which is metallic, hydrophobic or in layman's term 'afraid of water' or 'water hating' as others like to say. This chemical used will behaved, in a way, as a wax would when you applied it to your car. After wax (or hydrophobic ...
