Abstract

High-Fe bauxite is a typical refractory bauxite with extensive resources, and coal gangue is a solid waste produced during coal preparation. In this study, the co-roasting of high-Fe bauxite with coal gangue for iron and aluminum recycling was explored. The optimum conditions for co-roasting were roasting at 750 °C for 50 min with 40% coal gangue, and 70.55% particles with size <37 µm. Through magnetic separation, iron ore concentrate with 55.09% TFe and a recycling rate of 82.73%, and aluminum-rich products with Al2O3 of 21.67% and a recycling rate of 75.55% were produced. Based on the analysis of materials, hematite was transformed into magnetite, and diaspore was transformed into Al2O3 through co-roasting. Therefore, the co-roasting of high-Fe bauxite and coal gangue is a promising process for recycling iron and aluminum.

摘要

高铁铝土矿是一种储量巨大的典型难选铝土矿, 而煤矸石是选煤过程中产生的固体废弃物。本研究提出将高铁铝土矿与煤矸石共焙烧回收铁铝的方法。确定共焙烧的最佳条件为焙烧温度750 ℃、焙烧时间50 min、煤矸石配比40% 及磨矿粒度<37 µm 的占70.55%。焙烧产品经过磁选管磁选, 最终能得到总铁品位为55.09%、铁回收率为82.73% 的铁精矿和Al 2 O 3含量为21.67%、铝回收率达75.55%的富铝产品。物相分析表明, 共焙烧过程能将高铁赤泥中的赤铁矿有效转化为磁铁矿, 将一水硬铝石转化为Al2O3。实验表明, 高铁铝土矿与煤矸石共焙烧是一种很有应用前景的铁铝回收工艺。
