The recovery of Ti from titanium slag by alu minum was investigated.After smelting,Ti-Si-Al alloy and slag with high content of alumina were obtained.It is indicated from the experimental results that the recovery of Ti from titanium-bearing blast furnace slag by aluminum is technically feasible.The effective enrichment and separation can be achieved in a short time.The main factors affecting the smelting results are temperature,time,contents of reducing agent aluminum and flux CaO.The effective enrichment and separation can be achieved with wslag:wAl=100:25.98 at 1 600℃ for 10 min.At the same time,adding CaO is helpful to achieve the separation of the alloy and slag.
