Mar 13, 1996· Abstract not available for EP0532633 Abstract of corresponding document: US5098583 In the process for beneficiating a crude kaolin by the method which includes a wet classification step to provide a classified kaolin fraction having a PSD such that at least 50% by weight thereof are of less than 1/2 mu m ESD and substantially by weight are of less than 10 mu m ESD; and one or more .

Kaolin clays are conditioned for the removal of colored titaniferous impurities by (A) first mixing the kaolin clay with a collector to condition the impurities, in the absence of a dispersant, but in the presence of sufficient water to yield a mixture having a solids content of at least 65 percent by weight and (B) then deflocculating the kaolin clay mixture at a pH of at least 4.0 with a ...

USE OF ALKOXYLATED AMINES AS COLLECTOR AGENTS . FOR ORE BENEFICIATION [0001] The present invention relates to the use of cationic collectors in flotation processes for the beneficiation of ores, more particularly in reverse flotation processes for the beneficiation of ores, specifically for the beneficiation of silicate-containing ores.

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

In addition, the smectite clay employed can be either crude (containing gangue or non-clay material) or beneficiated (gangue removed). The ability to use crude clay in the smectite-type clay of this invention represents a substantial cost savings, since the clay beneficiation process and conversion to the sodium form do not have to be carried out.

Physical beneficiation of rare earth bearing minerals by Pickering emulsification. • Oil-water emulsification is feasible without using any surfactants and pH modification. • Droplets are able to selectively capture REE minerals based on wettability. • The recovery around 50% in one stage emulsification with 2.9 enrichment ratio. •

Abstract. Kaolin is a rock composed mainly of kaolinite. It is used in many industrial segments, such as paper and ceramics. However, for these uses it is necessary to submit the ore to appropriate beneficiation, which generally involves magnetic separation and chemical bleaching, aiming to remove iron oxide and hydroxide, raising brightness index.
