摘要
为了综合回收利用徐州铁矿集团有限公司镇北矿区磁铁矿和赤褐铁矿混合矿资源,采用磁选-强磁选-焙烧磁选工艺对其进行了试验研究,结果表明:可获得铁品位65.46%,回收率93.95%的综合铁精矿品位,精矿产率约提高7%左右,原矿铁品位下降10%左右。
In order that synthesis recovering and utilizing blended ore resources of magnetite and limonite in Xuzhou iron mine group company limited, adopted magnetic concentrating- strong magnetic concentrating- baking magnetic concentrating technique to carry out experiment studying. Result makes known that, obtained synthesis iron concentrate class is 65.46%, recovery is 93.95%, the concentrate yield is enhanced 7% about, the class of primary mineral is dropped 10% about.
