最初我矿在生产中因受铜浮选流程的限制,二硫化钼精矿位品只达51％左右,回收率为51.37％。以后经过试验研究改变铜浮选流程,把铜浮选中矿单独处理,而把中矿直接送去浓缩不经铜钼浮选,即只选组选精矿。这祥做以后成续大有提高。二硫化钼回收率达到65～70％左右。精矿品位达到68～72％左右。改变流程后回收率(绝对数)较前提高了13.44％(总平均),精矿品位提高18.29％,改进的经过简述如后。一、总的情况芙蓉的矿石的类型是斯卡岩接触矿床。花岗闪长岩侵入石英砂岩,角闪岩及角页岩接触形成的矿体,其组合成份以黄铜矿为主。黄铁矿、磁铁矿及微量的辉钼
Initially, due to the limitation of copper flotation process, mine production was only 51% of molybdenum disulfide concentrate, with a recovery rate of 51.37%. After the pilot study to change the copper flotation process, the copper flotation of mineral processing alone, while the mine directly sent to concentrate without copper and molybdenum flotation, that is, only the election of the group selected concentrate. This is a great success after the continued improvement. The molybdenum disulfide recovery rate of about 65 to 70%. Concentrate grade reached 68 ~ 72%. After changing the process, the recovery rate (absolute number) increased by 13.44% (total average) and the grade of concentrate increased by 18.29%. The improvement was briefly described as follows. First, the general situation Hibiscus ore type is Schist rock contact with the deposit. The granodiorite intrudes into the ore body formed by the contact of quartz sandstone, hornblendite and hornblende, and its composition is mainly chalcopyrite. Pyrite, magnetite and trace molybdenum
