高炉渣制备系列精细化工品的技术研究
Preparation of a series of fine chemicals by blast furnace slag
摘要
Abstract
On the basis of previous works, preparation of a series of fine chemicals by blast furnace slag was researched further and deeply, and the process route was developed. The first product, gypsum, was obtained by sulphuric acid hydrolysis. The optimum conditions for preparing aluminum silicate were: water-slag ratio 7:1, pH 4.0 and adding small pieces of Al plates to remove iron. The optimum conditions for preparing magnesium aluminum spinel were: mass percent of urea 65% and amount of Na2S2O4 5%. The chemical composition of the three products was in accord with the relative standards.This process had the advantages of short flow, low cost, etc. Almost all valuable contents in the slag were used, and no residue was discharged. Thus, it had better environmental benefit.关键词
