PROCESS FOR TREATING NON-SULPHIDIC ORES WITH A COLLECTOR COMPOSITION CONTAINING A PRIMARY COLLECTOR AND A SECONDARY COLLECTOR AND PULP

摘要

the present invention relates to a process for treating non-sulfidic ores with a collector composition that contains a primary collector and a secondary collector, wherein the primary collector is selected from the group of amphoteric and anionic surface active compounds and the collector secondary is an ethoxylated fatty acid in which the average degree of ethoxylation is greater than 0 and less than 2, to the collector compositions suitable for use in the above process, and to the pulp comprising such collector compositions.
