生产辉钼矿精矿的可能性[据俄刊《选矿文摘》报道]对捷克腊科夫尼克地区古尔基矿床的钼矿石进行了浮选实验室试验。矿石含0.15%Mo、0.03%Cu、0.031%Pb、57.93%SiO_2。岩石被方解石碳化。矿石中除含有辉钼矿外,还含有黄铜矿、方铅矿、赤铁矿和磁铁矿。研究了矿石磨矿比、捕收剂量和矿石钼品位对钼精矿回收率的影响以及钼、铜和硫的浮选动力学。在磨矿粒度为65—70%—0.071mm 的条件下,钼的回收率最高。在捕收剂(Orfom MCO——石油加工产品)用量>30g/t 时,浮选泡沫产品的回收率较高。钼、铜、硫的回收率的增大取决于浮选时间的延长。钼和铜在9分钟时达到最大回收率,硫在4分钟时达到最大回收率。选择
Possibility of producing molybdenite concentrate [Flotation laboratory tests on molybdenum ore from the Gulki deposit in the Czech Republic, Kraków, Czech Republic, according to the Russian edition of “Mineral Digest”. Ore contains 0.15% Mo, 0.03% Cu, 0.031% Pb and 57.93% SiO 2. Rocks are carbonized by calcite. In addition to molybdenum ore contains molybdenite, but also contains chalcopyrite, galena, hematite and magnetite. The effects of ore grinding ratio, collector dose and molybdenum grade on molybdenum concentrate recovery and flotation kinetics of molybdenum, copper and sulfur were studied. The recovery rate of molybdenum is the highest when the grinding particle size is 65-70% -0.071mm. In the collector (Orfom MCO - petroleum processing products) consumption of> 30g / t, the recovery of flotation foam products higher. The recovery of molybdenum, copper and sulfur depends on the lengthening of flotation time. Maximum recovery of molybdenum and copper was achieved at 9 minutes, with sulfur reaching maximum recovery at 4 minutes. select
