ФЛОТАЦИОННЫЙ СОБИРАТЕЛЬ И СПОСОБ ЕГО ПОЛУЧЕНИЯ

摘要

FIELD: floatation dressing of non-sulfide ores. ^ SUBSTANCE: the invention is pertaining to the field of a floatation dressing of non-sulfide ores and may be used in production of floatation reagent-collectors on the basis of fatty acids. The floatation reagent-collector for non-sulfide ores is produced on the basis of saponated fatty acid. Before a saponification of a fatty acid it is heated up to 70-75° and at stirring action as a regulator of polymerizing inject a phenolic antioxidant Ahydol-1 in amount of 0.5-5 mass %. After the saponification process a produced collector may be added with sodium alkyl sulfate in amount of 4-5 mass %. The flotation collector possesses a high-efficient and high-selective floatation of the non-sulfide ores predominantly barite-containing ores. ^ EFFECT: the invention ensures production of floatation reagent-collectors on the basis of fatty acids. ^ 4 cl, 1 tbl, 2 ex
