改善天然矿物氧化铁红颜料色光的研究

STUDY ON IMPROVING COLOR AND LUSTRE OF NATURAL RED IRON OXIDE

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.
