摘要
Suggested is a process for the flotation of non-sulfidic minerals or ores, in which crushed crude minerals or ores are mixed with water and a collector to form a suspension, air is introduced into the suspension in the presence of a reagent system and a floated foam containing said non-sulfidic mineral or ores formed therein along with a flotation residue comprising the gangue, wherein the improvement comprises using as the collector polymeric esterquats, obtainable by reacting alkanolamines with a mixture of monocarboxylic acids and dicarboxylic acids and quaternising the resulting esters in known manner, optionally after alkoxylation.
