Cationic flotation of quartz from an artificial mixture
Jan 01, 1988The cationic flotation of quartz was carried out from an artificial mixture (1:1 by weight) of fine grained ( − 10 μm) quartz and hematite, using hexylamine acetate (HAA) and dodecylamine acetate (DAA) as collectors. Selective flotation of quartz was possible in the pH range 9–10 using HAA.

FLOTATION OF QUARTZ AND HEMATITE: ADSORPTION
The flotation recovery of quartz is nearly 90% with 1 × 10 -4 M C 12 amine and above which 100% recovery is attained. However in case of anionic collectors quartz is not floated in the pH range studied and the maximum recovery about 25% is

Activation mechanisms of quartz flotation with calcium
Jan 02, 2022in general, the flotation of quartz has two common methods: cationic flotation using fatty amines, quaternary ammonium salts, ether amines, etc., and flotation with metal ions activation and using anionic collectors, such as sodium oleate, sodium alkyl sulfonate, and sodium alkyl sulfate with metal ions as activators, such as ca 2+, cu 2+, pb 2+,
