【摘要】 利用海绵钛生产中回收的低浓度盐酸(浓度约为18％-25％)与硫酸渣反应制取三氯化铁,在进行的正交实验中可得出最佳处理工艺条件是反应温度90℃,液固比为3:1,时间5 h,铁的浸出率为63．8％,实验同时表明该研究可实现二次资源的综合利用。更多还原

【Abstract】 The low density hydrochloric acid (density is approximately 18%-25%) recycled from titanium factory producing the sponge titanium in chlorination was used to react with pyrite residue to produce FeCl3. The experimental result indicates that the best condition to handle technology is that the reaction temperature is 90℃, liquid-solid ratio is 3:1, time is 5 h, and the ratio of leaching of iron is 63.8%. At the same time, this reaction can achieve its comprehensive utilization of two-resources of low density hydrochloric acid and pyrite residue.更多还原
