硫酸法由富钛高炉渣中提取钛

攀枝花含钛高炉渣是一种重要的、待开发利用的钛资源。本文介绍采用以含钛高炉渣进行“选择性分离”后的富钛精矿为原料 ,研究硫酸法提取钛过程中渣酸比、温度、渣粒度以及硫酸浓度对钛元素酸解率的影响 ,钛元素最高酸解率可达 98%以上 ,为实现从高炉渣中回收钛提供了理论基础。

Recovery of Titanium from Rich Titanium Blast-Furnace Slag by Sulfate Method

The blast furnace slag in Panzhihua is a kind of important titanium resource,which contains rich titanium and can be exploited comprehensively. The method of recovering titanium from the slag was described in this paper. The conditions of recovering titanium by use of sulfate method including the ratio of slag to H 2SO 4, reaction temperature,particle size of the slag and the concentration of H 2SO 4 are examined in detail. Acidolysis ratio of 98% can be obtained under the optimal conditions.
