Clean and Efficient Recovery of Valuable Metals from Bismuth Sulfide Concentrate by Low-Temperature Alkaline Smelting
The traditional bismuth sulfide concentrate smelting process had the problems of low direct recovery rate of metallic bismuth, low extraction rate of associated valuable metal elements, and SO2 flue gas pollution. In this paper, alkaline smelting has been proposed to realize one-step extraction of m...

| description | The traditional bismuth sulfide concentrate smelting process had the problems of low direct recovery rate of metallic bismuth, low extraction rate of associated valuable metal elements, and SO2 flue gas pollution. In this paper, alkaline smelting has been proposed to realize one-step extraction of metallic bismuth from bismuth sulfide concentrate and immobilization of sulfur in molten salt. The influences of smelting temperature, Na2C03 addition, and reduced coke dosage on the direct recovery rate of metallic bismuth and sulfur-fixing rate have been investigated in detail.
