SLon高梯度磁选机分选刚果(金)某氧化钴矿的试验研究

On the Application of Slon High-gradient Magnetic Separator in Cobalt Oxide Mine

刚果(金)某氧化钴矿属于风化壳型钴土矿床,虽然钴品位高达1.64%,但是矿物组成复杂,大量钴以吸附嵌晶态赋存于黏土矿物含锰混晶中。试料采用预先擦洗分级,脱除大量低品位细粒(-0.125 mm)后,应用SLon高梯度磁选机磁选工艺,经小型试验获得了可直接用于湿法冶炼的钴粗精矿。粗精矿含钴7.82%,钴的总回收率达59.43%,磁选作业回收率达81.16%。

A cobalt oxide mine in Congo is soft weathering complicated , despite its high concentration （1.64 %）. Much crust cobalt deposit. The mineral composition is of cobalt exists as adsorb and embed crystalloid in clay mineral which includes manganiferous mixed crystalloid. After preliminary scour classification, the low grade ore （-0.125 mm） was removed. Applying SLon Magenetic Separator on the remaining ore for small-scaled experiments, the raw cobalt concentrate, with cobalt grade 7.82 %, cobalt recovery rate 59.43 %, SLon Magnetic Separator recovery rate 81.16 % which can be used in hydrometallurgy directly, was obtained.
