中文摘要

为实现硼镁铁矿资源的高效综合利用，本文提出了一种硼镁铁矿钠化焙烧–湿磨浸出–磁选–碳分实现硼/铁高效分离的工艺。研究了焙烧参数包括：焙烧温度、时间、碳酸钠用量以及还原势CO/(CO+CO₂)对硼、铁同步分离指标的影响。在优化的焙烧条件下：焙烧温度850°C、焙烧时间60 min、碳酸钠用量为20wt%以及还原势CO/(CO+CO₂)为10vol%，92%的硼在湿磨过程中直接浸出到溶液中，约89%的铁通过磁选富集于磁铁精矿中，磁铁精矿的铁品位为62wt%。高品位磁铁精矿可以作为钢铁行业的原料。拉曼光谱和¹¹B核磁共振波谱结果表明硼在浸出液中以$ \mathrm{B}(\mathrm{O}{\mathrm{H})}_{4}^{-} $离子的形式存在，浸出液通过碳分–结晶制备出高纯硼砂产品。

Abstract

Abstract

To realize the comprehensive utilization of ludwigite ore, an integrated and efficient route for the boron and iron separation was proposed in this work, which via soda-ash roasting under CO–CO₂–N₂ atmosphere followed by grind-leaching, magnetic separation, and CO₂ carbonation. The effects of roasting temperature, roasting time, CO/(CO+CO₂) composition, and Na₂CO₃ dosage on the boron and iron separation indices were primarily investigated. Under the optimized conditions of the roasting temperature of 850°C, roasting time of 60 min, soda ash dosage of 20wt%, and CO/(CO+CO₂) of 10vol%, 92% of boron was leached during wet grinding, and 88.6% of iron was recovered during the magnetic separation and magnetic concentrate with a total iron content of 61.51wt%. Raman spectra and ¹¹B NMR results indicated that boron exists as ${\rm{B}}({\rm OH})_{4}^{-}$ in the leachate, from which high-purity borax pentahydrate could be prepared by CO₂ carbonation.
