摘　　要：介绍了以废铁渣为主要原料与工业硫酸反应制备三氧化二铁,产生的废液加氧化钙生成副产物硫酸钙的工艺。解决了废铁渣的占地及给环境带来的污染问题。属废资源开发,变废为宝,产率在80%左右。产品用于工业,有一定的经济价值。This article introduced the process, in which waste iron residue, as the main raw materials, responds with industry sulfuric acid to produce discard output liquid add the craft of the born an outcome sulfuric acid calcium in calcium oxide. This can resolve the problem that scrap iron residue covers area and the environmental contamination. Its production rate is about 80%. The product can be used in industry and has an economical value.
