Basic Study on Vanadic Titanomagnetite Milling in Panzhihua

With the laser microscopic spectral analysis,spectrum quantitative analysis,electronic quantitative analysis,the chemical compositions,phase component and the storage state of usefull elements of vanadic titanomagnetite are in detailed researched.According to the compositions and phase of the vanadic titanomagnetite,appropriate scheme is formulated.Through broken and grinding in a closed road,the original ore carry on with two times of magnetic separation and one time of scavenging,then the ferrovanadium concentrate is gained.Granulous ilmenite is gained from magnetic separation tailings,satisfactions process:chute and spiral milling-flotation(sulfur minerals)-electrical select process.The basic experiment study is carried on in the laboratory.Experiments indicate that when the grinding granularity rise up to 0.2 mm(the outside of the mine is 0.15 mm) and the iron grade in ferrovanadium concentrate is about 55%;titanium mineral and pyroxe ne have been separated by the electrical select and ilmenite of high titanium content is gained.when coarse grains gained in floatation are grinded again,the cobalt content in the sulphur cobalt concentrate can rise up to 0.38%.
