摘要:
这是一篇地球科学及矿物加工工程领域的论文。伊朗霍尔木兹海峡沿岸钾盐矿赋存于寒武系Hormuz组盐层内,矿体受褶皱构造控制,形态复杂,形成的“S”形、顶厚、平卧等褶皱形态,矿石类型为氯化物型钾石盐矿石,主要矿石矿物为钾石盐,KCl含量2.5%~35.20%。研究区寒武系为泻湖相沉积,波斯湾含钾卤水持续蒸发形成一套含钾石盐海相蒸发岩序列,受阿尔卑斯早期构造活动影响,含钾盐层受挤压作用,形成盐底辟构造。采用一次粗选一次扫选二次精选及浮选精矿加洗涤的实验流程,可以获得了含KCl(湿基87.44%,干基91.14%)或KCl(湿基88.97%,干基93.69%)两种的氯化钾产品,KCl回收率分别为85.93%、81.70%,钾盐选矿指标良好。
Abstract:This is an article in the field of earth sciences and mining processing engineering. 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.
