<p>In the flotation of insol. components of potash ore, the ore pulp is conditioned with (per t.potash ore) at least 0.4 g aliphatic amine collector for the insolubles and at least 5 g flocculating agent, the collector being selected from prim. and sec. aliphatic mines and prim. ether amines. - Also claimed is a process for flotation of sylvite from potash ore, using 20-500 g (per t. potash ore) of a 8-24C prim. aliphatic amine as collector for sylvite, in which the insoluble components of the potash ore are removed, prior to sylvite flotation, by frothing in the presence of (per t.potash ore) 0.4-25 g of the prim. aliphatic amine collector and at least 5 g of an acrylamide flocculating agent.</p> |
