摘要: 论述了用攀枝花钛精矿制取高品位富钛料的3种途径:钛精矿盐酸浸出法制造人造金红石、钛精矿-钛渣盐酸浸出法制造钛渣富集物和钛精矿硫酸浸出法制造人造金红石;对这3种方法的优缺点进行了分析比较。Abstract: Three methods of preparing high grade titania feedstock from Panzhihua titanium concentrate are reviewed. These methods include:(a)preparing synthetic rutile by leaching the titanium concentrate with hydrochloric acid, (b)preparing upgraded slag(UGS) by leaching the slag made from smelting the titanium concentrate with hydrochloric acid, and (c)preparing synthetic rutile by leaching the titanium concentrate with sulphate acid. The advantages and disadvantages of these methods are also presented.
