Craft mineralogy research of chalcogens in Panxi vanadium-titanium magnetite

After detailed mineral research of sample ore in Panzhihua,Baima,Hongge and Taihe,the Big Four Panxi Vanadium-Titanium Magnetite mining area,we find out the assigned state and distribution of chalcogens in ores:multiply utilizable minerals such as Co,Ni,Cu contained in pyrite,pentlandite,skutterudite,their embedded particle size is imperceptibly and the average particle size is less than 0.074mm.But they are closely related with pyrrhotite and pyrite,mostly occurrence in magnetic minerals such as pyrite and pyrite,and then in closely inlaid with titanium magnetite pyrite,only little part in the form of fine mineral occurrence in iron minerals and silicate phase,and pyrrhotite is the primary sulfide into concentrate during dressing processes.Combined with utilization status of chalcogens and research materials of its process mineralogy,we think it’s feasible and in line with the actual production in present processing technology,to aim at distinguishing pyrrhotite and pyrite,further improve the sulphur concentrate’s grade and recovery as the carrier of Co,Ni,Cu,and finally form up available sulphur concentrate containing Co,Ni and Cu with high grade.
