摘要
综合论述了国内外复杂含钪资源的提钪冶金工艺。详细介绍了从复杂低品位矿如钪钇石、稀土矿物、铀矿和镍矿中提钪的工艺以及从冶炼残渣如赤泥、含钛烟尘、钨矿渣和合金渣中提钪的工艺,分析评价了各工艺的效果及存在问题,提出了将钪作为辅助提取元素与主资源加工工艺相结合,包括矿物预处理、浸出、溶剂提取、沉淀和煅烧的提钪冶金工艺得到最广泛应用,并对未来提钪工艺进行了展望,认为实现选择性浸出和寻找高效的萃取剂,是今后提钪工艺得以突破的关键。
Metallurgical processes for scandium recovery from various resources domestic and overseas are re- viewed. The processes for scandium recovery from complex lower grade ore such as thortveitite, rare earths, urani- um and nickel ores and from residues and smelting slag such as red mud, titanium dust, tungsten slag and alloy scraps are introduced. The effects and problems of the processes are analyzed and evaluated. The methods combi- ning scandium recovery as by-product with main resource processing technology are proposed, which include com- monly used techniques such as ore pre-treatment, leaching, solvent extraction, precipitation and calcination. New technologies for scandium recovery such as efficient extraction solvent and selective leaching solvent extraction would play key roles for breaking through in scandium recovery process.
