摘要

A flotation collector composition comprises a combination of fatty acids, amidocarboxylic acids or amidosulfonic acids and partial esters of phosphoric acid and alkoxylated alcohols. The collector composition is used for upgrading nonsulfide minerals containing alkaline earth metals by froth flotation. Minerals such as apatite, calcite, scheelite, fluorspar, magnesite and baryte can be separated from the gangues using the collector composition.
