Abstract:In order to realize the enrichment and utilization of titanium in blast furnace slag, the technical means of slag titanium enrichment are studied, and the possibility of slag titanium resource utilization is analyzed. The results show that titanium in slag can be enriched in the form of titanium tetrachloride, ferrotitanium alloy, titanium dioxide, titanium carbide and selective precipitation. Selective precipitation enrichment is a green enrichment technology. Titanium resources in slag can be used as building materials, glass materials, functional materials and fertilizers. The technological processes of slag titanium extraction are complex, easy to pollute the environment and high cost. Some low titanium slag is directly used in building materials or fertilizers, the reuse of high titanium slag after enrichment by selective precipitation technology is the key direction for comprehensive utilization of titanium containing slag in the future.
