    A process for the recovery of mineral values by froth flotation in an aqueous medium employing a novel frother. frothers prepared by michael addition between alpha, beta-unsaturated ethylenic compounds and either alcohols, amines or mercaptans or by the condensation of hcn, aldehydesketones with either alcoholics, amines or mercaptans have been found to be effective in the froth flotation.

    Frothers froth flotation

    Frothers froth flotation. the importance of frothers in mineral flotation is widely acknowledged in the mining industry. frothers perform the following key functions in the froth flotation process reduce surface tension of the liquid-gas interface to enable froth formation hinder coalescence in order to stabilize bubble.

    Us5106489a - zircon

    This invention relates to a method for recovering a bulk concentrate of zircon and a bulk concentrate of rutile-ilmenite from dry plant tailings. a process has been discovered for froth flotation by manipulating the surface charges of dry plant tailings. conditioning reagents, sulfuric acid to lower the ph corn starch to coat the minerals to be depressed sodium fluoride to activate the.


    After the flotation begins, an additional amount of the starch depressant can be added based on the color of the froth observed during the flotation process. for example, if the froth becomes black in color then ilmenite and rutile are being pulled into the froth and an additional amount of starch can be added to depress the ilmenite and.
