Oxide minerals such as mineral iron and mineral calcium are enriched by separating the siliceous species by foam floatation. As the collecting reagent in the process, a combination of ether diamine and fatty amine is used. The procedure achieves a substantial decrease in the degree of contamination without lowering the requirements for good yield. A means for carrying out the method contains a combination of an ether diamine and a fatty amine, preferably a fatty diamine, where the ether diamine is present in excess weight and the ratio between the ether diamine and the fatty amine is greater than 1.0:1. |
