Method for deep roasting arsenic removal of arsenic-containing material

The invention discloses a method for deep roasting arsenic removal of an arsenic-containing material, and belongs to the technical field of non-ferrous metallurgy. The fine grinded arsenic-containing material is evenly mixed with a proper quantity of chlorinating agents and water, pelletizing is carried out to obtain pellets, then the pellets are fed into a roasting furnace after being dried, roasting is carried out by controlling the atmosphere in the furnace, and roasted ore with the arsenic content being lower than or equal to 0.1% is obtained. According to the method, chloride such as calcium chloride, sodium chloride and magnesium chloride serves as roasting arsenic removal flux, roasting is carried out in a weak oxidation atmosphere or a weak reduction atmosphere, arsenic is converted into the form of arsenic chloride easy to volatilize so as to be removed from the arsenic -containing material, the process is simple, the arsenic removal rate is high, and the quality of the roasted ore is good.
