Potash ore occurs in the salt layer of Cambrian Hormuz Formation, The ore body is in dancing band with great thickness variation. The ore type is chloride-type sylvite ore, the main ore mineral is sylvite, with KCl content of 2.5%～35.20%. The Cambrian is a lagoon facies deposit. The continuous evaporation of potassium-bearing brine in the Persian Gulf formed a series of marine evaporite sequence containing potassium salt.Affected by the early Alpine structureactivity, the salt layer was compressed to form a salt diapir structure.Using the test flow of one roughing, one scavenger, two concentrating and Coarse ore washing, good test indexes have been achieved, and potassium chloride products containing 87.44% KCl (wet basis) (91.14% dry basis) or 88.97% KCl (wet basis) (93.69% dry basis) can be obtained, with KCl recovery rates of 85.93% and 81.70% , respectively.
