tetradymite

Tetradymite is a Te , Bi sulfide mineral which is usually difficult to form an independent one .

辉碲铋矿是一种较难独立成矿的碲硫化物。

It was revealed that gravity recovered parts of the tetradymite , but the total recovery rate and the Te grade of gravity concentrates were a little low .

重选研究发现可以回收一定量的辉碲铋矿，但是总的回收率和精矿碲品位较低。
