摘要/Abstract

摘要： 提出了预氧化电炉钛渣活化改性-选择浸取制备金红石的工艺，探讨了改性剂、渣剂比、活化改性温度及时间、预氧化渣粒度和酸浸制度对人造金红石中TiO2含量的影响. 结果表明，Na2CO3是较理想的改性剂，温度900℃、时间120 min、渣/改性剂质量比为5:1的条件下进行活化改性，产物经选择性浸取、洗涤、水解与煅烧，可得到纯度为92%的人造金红石，满足氯化法生产的钛白要求.

Abstract: A new process of activation modification-selective leaching for titanium-containing slag titanium-containing slag to prepare synthetic rutile was presented. The effects of modifier, ratio of slag to modifier, activating temperature, activating time, particle size of the preoxidation slag and acid leaching system on the content of synthetic rutile TiO2 were investigated. The results show that Na2CO3 was a relatively ideal modifier, when the activation reaction process was carried out under the conditions of temperature 900℃, activating time 120 min and mass ratio of slag to modifier 5, high purity synthetic rutile TiO2 of about 92% was obtained after high pressure acid leaching-washing-hydrolysis-calcination process from activating product, which meets the requirements of titanium dioxide pigment by the chlorination process in industry.

Key words: preoxidation titanium-containing slag, activation modification, elective leaching, synthetic rutile
