Composite sintering process had been investigated on the high titanium magnetite concentrate in order to address the issues of low-strength,high-return-rate and low-yield of sinter,adopted. It is found out that mix moisture has the greatest effect on the integrated index,followed by height of material layer. Compared with that of referenced sintering process,utilization coefficient with optimal sintering increases by more than 20%,and sinter strength and product rate increase by 3% and 5%,respectively.The volume fraction of ferrite in sinter increases by 4%~5% and metallurgical properties of sinter is improved at the different degrees.
