摘　　要：以硫铁矿烧渣为主要原料,在对目前硫铁矿烧渣回收及利用现状进行综合考察的前提下,结合实际的研究条件,通过直接混酸浸出、净化工艺制得了硫酸亚铁溶液,并浓缩、冷却结晶得到接近化学试剂纯的硫酸亚铁晶体,以此为原料,采用氧化沉淀法制取铁黄。Our study based on a detailed investigation of present utilization and recovery of pyrite, according to the real experiment condition, the FeSO4 solution was obtained from pyrite cinders by deoxidized baking, the sulfuric acid pickling and purifying process, an aqueous ferrous sulfate solution was then obtained after purifying the reducing solution, FeSO4·7H2O was crystallized from the ferrous sulfate by concentrating and cooling.
