最近,曾对云龙县漕涧锡矿选矿流程作了查定。综合指标为:原矿含锡0.23％、粗精矿品位24.48％,尾矿品位0.06％;粗选回收率72.83％。粗精矿经脱硫、脱砷处理后,获得含锡45％,对原矿回收率70％的合格精矿。漕涧锡矿所处理的矿石对象为脉锡矿,露采、坑采各半,原矿平均含锡0.2～0.3％,物质组成复杂,锡石与杂质矿物嵌布緻密,杂质矿物含硫、砷、铁量高。对于此种类型的矿石,能够获得上述选矿指标,在国内同
Recently, Yunlong County Caojian tin ore beneficiation process was identified. The comprehensive indexes are as follows: the raw ore contains 0.23% of tin, the crude concentrate grade is 24.48% and the tailings grade is 0.06%; the crude selection recovery rate is 72.83%. Crude concentrate after desulfurization, arsenic removal, access to 45% tin, ore recovery of 70% of the qualified concentrate. The ore objects processed by Caojian Tin Mine are vein tin ore, with half open pit mining and pit mining. The average ore containing tin is 0.2-0.3%. The material composition is complex. Cassiterite and impurity minerals are densely embedded. The impurity minerals contain sulfur and arsenic High iron content. For this type of ore, to obtain the above dressing indicators, the same in the country
