摘要/Abstract

摘要： 硅微粉是一种重要的无机非金属材料,主要由石英砂或岩石经过破碎、粉磨、分级、提纯等一系列加工过程而得到,通常具有较高的纯度和较小的粒径分布。本文以福建某钨矿重选尾矿综合利用分离出的石英产品为原料,通过浮选-酸浸-超细磨-离子清洗-改性等工艺成功制备出超细硅微粉产品。结果表明,超细硅微粉的主要化学成分(质量分数)为SiO₂(99.820 0%)、Fe₂O₃(0.001 8%)、Al₂O₃(0.041 0%),水萃取液的pH值为7.08,电导率为6.26 μS/cm,Na⁺浓度为0.24 ppm(1 ppm=10^-6)、Cl^-浓度为2.94 ppm,吸油值为21.36 g/100 g,这些指标均优于《电子及电器工业用二氧化硅微粉》(SJ/T 10675—2002)电子级活性硅微粉的质量要求。本研究为矿山金属尾矿高值化有效利用提供了思路和方法,对于促进资源循环利用和环境保护具有积极的意义。

Abstract: Silica micropowder is an important inorganic non-metallic material, which is mainly obtained from quartz sand or rock through a series of processes such as crushing, grinding, grading and purification. It usually has high purity and small particle size distribution. In this paper, the ultrafine silicon micropowder product was successfully prepared by flotation, acid leaching, ultrafine grinding, ion cleaning and modification using quartz product separated from gravity separation tailings of tungsten mine in Fujian as raw material. The results show that the main chemical composition (mass fraction) of ultrafine silicon micropowder is SiO₂ (99.820 0%), Fe₂O₃ (0.001 8%), Al₂O₃ (0.041 0%), the pH value of water extract is 7.08, the conductivity is 6.26 μS/cm, the concentration of Na⁺ is 0.24 ppm (1 ppm=10^-6), the concentration of Cl^- is 2.94 ppm, and the oil absorption value is 21.36 g/100 g. These indexes are better than the quality requirements of electronic grade active microsilicon powder of “Silicon dioxide powder for electronic and electrical industry”(SJ/T 10675—2002). This study provides ideas and methods for the effective utilization of high-value metal tailings in mines, and has positive significance for promoting resource recycling and environmental protection.
