Study on process mineralogy of Chromium in the West Panzhihua vanadium titanium magnetite

After detailed process of mineral research on PanXi vanadium-titanium magnetite core sample in Panzhihua,Baima,Taihe and Hongge,the Big Four mining areas,we think chromium in Hongge mining area should be distinguished with others:it has five output form,although contained in titanium iron ore with highest level,it mainly occurs in chromium-titanium magnetite and vanadium-titanium magnetite in Hongge(further research on single mineral chromium increase),while it mainly occurs in titanic magnetite in other mining areas.In Hongge mining area,chromium-titanium magnetite and vanadium-titanium magnetite are the main carrier of chromium element,and also the main recycling mineral of iron concentrate.Combined with current utilization of chromium,we believe there is still minor promotion space of iron concentrate grade and recovery with current mineral processing technology.During improving the iron concentrate grade and recovery of vanadium,in the meantime to get chromium ore dressing recovery rate improved.
