USE OF AN EMULSIFIER IN A FLOTATION AGENT COMPOSITION Russian patent published in 2019 - IPC B03D1/08 

FIELD: chemistry.

SUBSTANCE: disclosed invention relates to a composition of a floatation agent used for froth flotation of non-sulphide ores, particularly phosphate ores. Flotation reagent composition suitable for use in froth flotation of non-sulphide ores contains a surface-active primary floatation agent selected from a group consisting of fatty acids, sulphonates, alkyl phosphates, alkyl sulphates and a secondary floatation agent containing a mixture of at least one compound (i) selected from a group of alkoxylates of branched fatty alcohols with 12–16 carbon atoms, having a branched degree of 1–3.5, with a degree of ethoxylation of up to 4, and at least one compound (ii) selected from a group of alkoxylates of non-ionic hydrocarbon compounds with a degree of ethoxylation higher than 3, where if both compounds (i) and (ii) are ethoxylated alcohols, the mixture has a bimodal distribution degree of ethoxylation.

EFFECT: higher efficiency of froth flotation.
