摘要:
通过对攀西钒钛磁铁矿矿物结构及攀西钛精矿选钛工艺研究, 同时采用XRD、扫描电镜对攀西钛精矿进行深度剖析, 得出在攀枝花钛精矿中主要元素分布及杂质元素的赋存状态。攀西钛精矿是以偏钛酸铁 (FeO·TiO2) 晶格为基础, 含有Mg、Mn等氧化物杂质的固溶体, 主要杂质元素Si、Ca、Mg、Al、Fe、Ti等物质以一种或多种氧化物形式固溶于钛铁矿伴生相硅酸盐中。针对不同用途, 提出通过深度解粒, 调整钛精矿选别工艺参数, 可生产出高品质的钛精矿, 实现高附加值利用。
Abstract:
Through the research of the mineral structure of vanadium-titanium magnetite and the mineral process technology of titanium concentrate in Panxi area,the distribution of the main elements and the state of the impurity elements were concluded by deeply profiling of the titanium concentrate using XRD and SEM.Panxi titanium concentrate based on the lattice of metatitanic acid iron（FeO·TiO2）,is a solid solution with Mg and Mn,etc.The main impurity elements,such as Si,Ca,Mg,Al,Fe and Ti,etc.,are dissolved as one or more types of oxide,in silicate which is associated with ilmenite.According to different purposes,the deeply graining and adjusting the parameters of separation technology for ilmenite concentrate were put forward to produce high quality ilmenite concentrate for realizing high value-added utilization.
