摘要
通过选择Fe2O3含量高、色泽较好的优质赤铁矿,对赤铁矿原料进行选矿提纯以提高Fe2O3含量以及对天然氧化铁红进行适度的煅烧。
Through study,this article presents choosing high quality hematite that has high content of Fe 2O 3 and good color and lustre,dressing and purifying hematite raw material to increase the content of Fe 2O 3 and calcinating appropriatly,all these three steps can effectively improve color and lustre of natural red iron oxide.
