为了从各种含铋精矿及冶炼过程产出的含铋物料中回收铋,我厂采用混合熔炼法从铋精矿和含铋渣料中生产出符合精炼要求的粗铋。铋精矿包括硫化矿、硫化铋与氧化铋
In order to recover bismuth from various bismuth-bearing materials containing bismuth concentrates and smelting processes, our factory produces mixed bismuth from bismuth concentrates and bismuth-containing dregs to meet the refining requirements by a mixed melting process. Bismuth concentrates include sulphide ores, bismuth sulphide and bismuth oxide
