摘 要: 以攀枝花钢铁集团的含钛高炉渣为原料,在氩气气氛保护下进行高温碳热还原后,将剩余的渣用盐酸浸出。实验通过对不同温度、不同浓度的酸浸出研究,得到酸浸动力学曲线。结果表明,酸浸反应的控速环节是界面化学反应,得到反应的表观活化能为23~32 kJ/mol.
关 键 词: 冶金物理化学;含钛高炉渣;酸浸;HCl;动力学

Abstract: The kinetics of the leaching of carbothermic reduced titanium-bearing blast furnace slag from Panzhihua Iron and Steel Company with acid system under the protection of Ar atmosphere pressure was studied. The results show that the temperature and acid concentration have significant influences on leaching of carbothermic reduced titanium-bearing blast furnace slag by acid, kinetic curves of acid leaching were obtained. The experimental datas of leaching indicate that the rate-determining step of acid leaching reaction was interface chemical reaction. The apparent activation energy can be estimated to 23-32 kJ/mol.
Key words: metallurgical physical chemistry; titanum-bearing blast furnace slag; acid leaching; HCl; kinetics
