【摘要】 以辽宁某地钾长石为原料,根据有用矿物和杂质的不同性质,采用浮-磁联合的选矿工艺,通过单因素实验法,从磨矿细度、药剂制度和磁场强度等方面进行了除铁降硅选矿试验研究,获取了最优的选矿条件。试验结果表明,该工艺能有效地降低原矿中铁的含量、提高钾的品位,生产出符合工业要求的高档陶瓷原料。更多还原

【Abstract】 The experimental research was carried out to remove iron and improve the content of potassium in feldspar ores in Liaoning province by the techniques of flotation and high gradient magnetic separation according to the difference between the valuable mineral and impurities.By Single-factor test methods,the optimal conditions of dressing on grinding fineness,pharmacy systems and magnetic field strength was obtained.The results show that this method can work out effectively and the products can meet the quality requirement of high grade ceramic raw materials.更多还原
