铋矿物是我矿矿石中一种主要的伴生矿物。主要呈辉铋矿、黄铋矿和泡铋矿产出。出窿原矿含铋一般为0.04～0.05%;经脱泥、手选后,合格原矿含铋0.06～0.065%。二十多年来,对铋矿物的选收工艺流程做了几次较大的改进,逐渐形成了目前这一选别工艺流程(见图)。
Bismuth minerals are one of the major associated minerals in mine ores. The main bismuth ore, yellow bismuth ore and bismuth ore output. Out of the mine ore containing bismuth is generally 0.04 to 0.05%; after desliming, hand-selected, qualified ore containing bismuth 0.06 ~ 0.065%. For more than two decades, several major improvements have been made to the process of beneficiation of bismuth minerals, and the process of sorting by now has gradually taken shape (see figure).
