Research on New Technology of Making High-grade Titanium-rich Material from Self-reduced Pellet of Titanium Concentrate by Microwave Reduction

A new technology for preparing rich titanium product,which includes microwave reduction-mineral separation-microwave leaching,was put forward on the basis of the abundant situation of titanium mineral resource in Panzhihua-Xichang zone and the advantages and disadvantages of actual productive methods on making rich titanium product.The heating curve of self-reduced pellet of titanium concentrate was measured.The appropriate technological parameters including the content of additive 5%~6%,the milling time of 20 min were determined.Experiments were conducted on the whole flow sheet and the TiO₂ content in titanium rich product was 96.08% under the above condition.
