在红岭矿区细脉浸染型钨钼矿石伴生的钼矿物可选性试验中,针对原矿品位低,要求富集比高的特点,我们进行了“分支浮选”和“通常浮选”对比试验,结果表明,“分支浮选”法最终钼精矿品位提高1.8%,回收率提高4%;而且处理每吨原矿还可节省煤油25克,松醇油15克,硫化钠200克。(一)矿石性质矿石的矿物含量(%)如下:白钨矿0.1033,黑钨矿0.0622,辉钼矿0.033,黄铜矿和黄铁矿0.317,磁黄铁矿0.122,辉铋矿0.006,毒砂0.003,磷灰石0.096,萤石0.332,电气
In the feasibility test of molybdenum mineral associated with the veinlet disseminated tungsten-molybdenum ore in Hongling mining area, we conducted the comparative tests of “branch flotation” and “normal flotation” for the characteristics of low ore grade and high enrichment ratio The results showed that the “flotation” method eventually increased the grade of molybdenum concentrate by 1.8% and the recovery rate by 4%. Besides, it also saved 25 grams of kerosene and 15 grams of pine spirit and 200 grams of sodium sulfide per ton of ore. (I) Ore properties The ore mineral content (%) is as follows: scheelite 0.1033, wolframite 0.0622, molybdenite 0.033, chalcopyrite and pyrite 0.317, pyrrhotite 0.122, bismuthinite 0.006, Sand 0.003, Apatite 0.096, Fluorite 0.332, Electrical
