Method for chloridizing and roasting silicate mixture
The invention discloses a method for roasting a silicate mixed raw material by chloridizing, which comprises the following steps of: roasting uniformly mixed powder of a silicate mixture and chlorine salt in a water vapor atmosphere, and simultaneously leading out flue gas discharged from the mixture. According to the method, sodium chloride or calcium chloride and silicate raw materials are mixed, ground and roasted in a water vapor atmosphere, chlorine salt is converted into oxide to be introduced into silicate, hydrochloric acid is prepared or valuable metal in the silicate is recycled, and heavy metal is removed. The method has important significance on treatment and comprehensive utilization of the silicate-based solid waste residues, extraction and recovery of valuable metals and environmental protection.
本发明公开了一种用氯化焙烧硅酸盐混合原料的方法，在水蒸汽气氛中焙烧硅酸盐混合物与氯盐的均匀混合粉体，同时将从混合物中排出的烟气导出。该方法将氯化钠或氯化钙与硅酸盐原料混合粉磨后在水蒸汽气氛下焙烧，将氯盐转化为氧化物引入硅酸盐中，同时制备盐酸或回收硅酸盐中的有价金属，脱除重金属。该发明对硅酸盐基固体废渣的处理与综合利用、有价金属的提取回收和环境保护有重要意义。
