鄂东某褐铁矿大部分矿石铁品位在40%左右,并含有较高的硫,一直没有得到较好的利用。采用Slon高梯度磁选机可以使精矿品位提高到53.18%,回收率达到82.89%。为了配合大型冶炼厂的要求,还对该磁选精矿进行了焙烧试验,结果表明,在较优的条件下,可以得到品位65%以上的优质铁精矿。 Most of eastern limonite iron ore ore grade is about 40%, and contains high sulfur, has not been better use. Using Slon high gradient magnetic separator can make concentrate grade increased to 53.18%, the recovery rate reached 82.89%. In order to meet the requirements of large-scale smelters, the magnetic separation concentrates were also roasted. The results show that high-quality iron concentrates with a grade of more than 65% can be obtained under the optimal conditions.
