In order to promote the enrichment of titanium component in perovskite phase, based on the technology of selective precipitation, the slag is supposed to be oxidized.
为使含钛高炉渣中的钛组分富集于钙钛矿相中，基于选择性析出技术，需要对炉渣进行氧化处理。

For the route of selective separation and enrichment with sodium oxide, it is very difficult for one-step route to produce quite pure enriched slag.
