摘要
白云鄂博富钾板岩作为Fe-Nb-REE矿床的围岩,钾资源储量巨大,是一类重要的非水溶性钾矿资源。试验样品的K2O含量为8.99%,TFe2O3含量为13.60%,S含量为2.89%,其主要物相为微斜长石、黑云母、石英、磁黄铁矿。采用湿法磁选-浮选流程对富钾板岩进行可选性研究。试验结果表明,弱磁分选得到了S含量为27.99%的磁黄铁矿产品;强磁分选得到了K2O含量为11.97%的钾长石产品;浮法分选得到了K2O含量为8.60%的黑云母产品。
Potassic slate as the surrounding rock of Fe-Nb-REE ore deposit in Bayan Obo is a kind of important insoluble potassium mineral resource. The experimental sample contains 8. 99% of K2 O,13. 60% of TFe2O3and2. 89% of S. And its principal minerals are microcline,biotite,quartz,and pyrrhotite. The magnetic separation and flotation separation experiments were designed for the potassic slate ore. The pyrrhotite with 27. 99% of sulfur was obtained under the low-intensity magnetic field. The microcline which contains 11. 97% of K2 O was separated under the high-intensity magnetic field. The biotite with content of K2 O 8. 60% was obtained in the flotation separation experiment.
