Experimental Research on the Mineral Processing Technology of a Low-grade Vanadium-titanium Magnetite
摘要
Abstract
A titano-magnetite ore containing 16.43％ Tfe and 4.70％ TiO2,belongs to the boundary ore.The ore composition is complex,ilmentite,titano-magnetite as the main metal minerals and pyroxene,plagioclase,hornblende and olivine as the main gangue minerals.The pre-separation-stage grinding separation flowsheet was developed based on the properties of the ore and the iron concentrate with Tfe grade of 57.58％ and recovery of 60.42％ can be obtained.The flowsheet of high-intensity separation-flotation was adopted for the tailings to recover the ilmentite,and the qualified titanium concentrate containing 46.23％ TiO2 with a recovery of 71.24％ is obtained.The combined flowsheet developed to recover the ilmentite and titano-magnetite realized the comprehensive ultilization of the ore.关键词
