US5047144A Process for the separation of minerals

The present invention provides a process for the separation of minerals by flotation in the presence of activators and suppressors. Activators are cation-active condensation products and suppressors are anion-active products of aminoplast formers, formaldehyde and amines, ammonium salts, acids or a sulphite, in combination with either an anion-active or cation-active tensides.

The collectorless flotation and separation of sulphide

1988-5-1 · Certainly plant observations of the collectorless flotation of sulphide minerals are common and molybdenum copper separation is certainly carried out in practice in the absence of collectors (Urizar and Rosas, 1979). It is also possible, by altering the nature of the charge in the ball mill, to selectively alter or control grinding Eh.

SEPARATION OF MICA FROM CLAY BY FROTH

Mica can be removed from clay with reasonable ease by gravimetric means or flotation when the clay is coarse. However, when the clay particles and micaceous impurities are fine, the separation is very difficult. Froth flotation with conventional ionic collectors is usually unsuccessful because mica and kaolin, both silicate minerals, have
