The Art of Talc Flotation for Different Industrial ...

This allows talc to exhibit an inherent hydrophobicity, which is the basis of the separation of talc, by flotation, from other ore constituents in mineral industry. However, the heterogeneous character of talc surface particles has a particular importance in flotation. The face/edge relationship, which depends on the particle size, deter-

Surface cleaning and oxidative effects of ultrasonication ...

Apr 15, 2017· The H 2 O 2 and nascent oxygen can oxidize the pyrite surface, which decreases the floatability of pyrite. In fact, in previous research, only the surface cleaning effect of ultrasonication was found for the flotation of oxidized sulfide minerals .The oxidative effect of ultrasonication was not observed for the oxidized pyrite.

Re‐evaluation of calcium silicate (E 552), magnesium ...

In both cases, talc ore is crushed and ground to a fine material before being mixed with water and a frothing agent (often a low‐molecular‐weight alcohol). Air is bubbled through the suspension which results in flotation and sequestration of talc particles and therefore removal of hydrophilic non‐talc impurities.

The interaction of guar gum and dextrin with talc has been investigated through adsorption, flotation, and electrokinetic measurements. The adsorption densities are independent of pH and the isotherms exhibit Langmuirian behavior. Higher adsorption density of guar gum onto talc is observed vis-à-vis that of dextrin. Pretreatment of talc with a complexing agent such as ...
