并针对石英和褐铁矿反浮选分离选择性较差的问题，开展了抑制剂的探索试验研究。
锰矿磁选机还可用于褐铁矿、金红石、铌钽矿等矿物的分选提纯。
一定程度上避免了褐铁矿选矿时产生的严重泥化现象，节水节能。
采用该磁选机选别可使褐铁矿的精矿品位达56%以上，回收率达65%以上；
1·The main gold-carrying mineral is quartz, pyrite and limonite.
主要载金矿物是石英、黄铁矿和褐铁矿。
2·A series of experimental studies were made on the effect of amide collectors with different length of carbon chain on flotation behaviors of hemimorphite quartz dolomite and limonite.
考察了不同碳链长度的胺类捕收剂对异极矿石英白云石和褐铁矿浮选行为的影响讨论了胺的碳链长度对捕收异极矿的影响。
3·The enrichment of Au mostly resulted with adsorption of illite and limonite in red clay.
金的富集主要受红色粘土中褐铁矿和伊利石的吸附影响。
4·The size distributions of diaspore, kaolinite and limonite ground in a ball mill in turn were studied.
本文研究了一硬水铝石、高岭石粘土岩和褐铁矿磨矿产物的粒度特性。
5·The main silver-bearing minerals were psilomelane, pyrolusite, limonite, galena, pyrite and sphalerite.
主要载银矿物有硬锰矿、软锰矿、褐铁矿、方铅矿、黄铁矿和闪锌矿。
