    A process for desliming sylvinite ores by a selective flocculation and froth flotation of the slimes is provided. The process involves treating the ore pulp with a high molecular weight acrylamide polymer to flocculate the slimes and then with a cationic collector for the flocculated slimes. The treated ore pulp is then subjected to froth flotation to float off the slimes.
