PROCESS FOR THE EXTRACTION OF MINERALS FROM NON-SULPHIDIC ORES BY FLOTATION

摘要

Proposed is a method of concentrating non-sulphidic ores by flotation, using as collectors sulphosuccinates of the formula (Ia) and/or (Ib), in which R<1> is a hydroxyalkyl group with 6 to 22 carbon atoms; R<2>CO is an acyl group with 6 to 22 carbon atoms; n is 0 or a number from 1 to 10; m is a number from 1 to 10 and M is sodium or potassium; optionally in combination with other anionic and/or non-ionic surfactants.
