在富钛精矿酸解所得的溶液中加入KCl,便形成以KAl(SO4)2为主的沉淀,过滤沉淀可以去除Al3+杂质。试验研究了KCl的加入量和溶液温度对Al3+沉淀率的影响。结果表明KCl的加入量大于溶液质量的20%、溶液温度为25℃时,Al3+沉淀率已达到75%以上,从而制备出了合格钛溶液。
在富鈦精礦痠解所得的溶液中加入KCl,便形成以KAl(SO4)2為主的沉澱,過濾沉澱可以去除Al3+雜質。試驗研究瞭KCl的加入量和溶液溫度對Al3+沉澱率的影響。結果錶明KCl的加入量大于溶液質量的20%、溶液溫度為25℃時,Al3+沉澱率已達到75%以上,從而製備齣瞭閤格鈦溶液。

KCl was added into rich titanium solution containing Al3+to produce KAl(SO4)2 as precipitate,Al3+in solution was removed.The quantity of KCl and temperature in solution influence deposition ratio of Al3+.The results show that precipitation of aluminium cations was more than75% when the mass of KCl was larger than 20% of the solution and temperature was 25℃,75% of Al3+ was removed.Thus the qualified titanium solution was got.
