一、前言为了综合利用钒钛磁铁矿资源,国内外研究了多种工艺流程。从目前的研究结果来看,较为合理的工艺之一是:在钒钛磁铁精矿中加入芒硝(Na_2SO_4)制成球团,使其
I. Introduction In order to comprehensively utilize vanadium-titanium magnetite resources, a variety of technological processes have been studied both at home and abroad. From the current research results, one of the more reasonable process is: adding vanadate (Na_2SO_4) into the vanadium-titanium magnetite concentrate to make it
