Removal and solidification rates of sulfur and arsenie were investigated detailedly in this research on the premise that slaked lime was taken as solidification reagent. The double-layered pellet roasting experiment would provide parameters and theoretical basis for industrial production. [Pg.20]

This roast experiment was carried out in the vertical furnace. In the process of double-layered pellet roasting, two gas-washing bottles containing sodium hydrate solution were placed in the outlet of equipment to prevent SO2 and AS2O3 diffusing into environment, hmer pellet calcine must be separated from solidification coat layer when double-layered pellets are cooled to room temperature. At the last, KB1O3 titration and classic BaS04 precipitation methods were used to analysis the percent content of arsenic and sulfur respectively. [Pg.21]
