Minus 0.10-m (4-inch) carnallite and minus 0.02-m (¾-inch) sylvinite ores were prepared for bench-scale flotation by stage-crushing and grinding through 1.70 mm (10 mesh) using a jaw crusher and roll crusher and then splitting the crushed ore into 1-kg (2.2-lb) charges. Stage crushing was used to avoid producing excessive fines, which …
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.

Froth stability is a critical factor for flotation and even a small decrease in froth stability causes a decrease in the recovery of desirable minerals (Hadler and Cilliers, 2009, Hadler et al., 2012, Kowalczuk and Drzymala, 2017a, Kowalczuk and Drzymala, 2017). Although frothers improve flotation rate and recovery, a very high frother ...
