ABSTRACT:
Insolubles are removed from sylvinite ores by froth flotation using a small amount of a primary, secondary or primary-ether alkyl amine as collector in combination with a flocculant. In the case of a primary alkyl amine, the collector may be the same as the collector used in the subsequent froth flotation to recover sylvite from the ore.
