摘要
研究了以硫酸分解镍渣,用氢氧化钠处理酸解渣制取高分散性白炭黑,以及用酸解液制备高纯氧化铁和镍精矿。将溶液进一步净化处理制取氢氧化镁。试验确定了最佳工艺条件及工艺流程。
The sulfuric acid was used to decompose the waste residue from nickel metallurgy ,sodium hydroxide was used to treat the sulfuric acid decompose residue for prepating sodium silicate and highly dispersed silica w hite .T he high-purity iron oxide and nickel concentrate can be obtained using the sulfuric acid solution .In addition ,after the further purify ,magnesium hydroxide products can be obtained by ammonia precipitation process .The best process conditions and technological process were determined .
