摘要: 为了查明黑龙江平安鳞片石墨矿工艺矿物学特征,在化学分析的基础上,采用自动矿物解离分析仪(mineral liberation analyser,MLA)系统研究了原矿矿物组成、粒度分布和矿石嵌布特性等.结果表明:原矿有价元素固定碳的质量分数为17.7%,主要以石墨形式存在.主要脉石矿物为长石、石英,其质量分数分别为34.32%,20.83%.该石墨矿大鳞片石墨(粒度大于0.15mm)的颗粒数占比为46.17%;当粒度为0.18mm

关键词: 鳞片石墨;工艺矿物学;矿物组成;粒度分布;单体解离度;嵌布特征

Abstract: To investigate the process mineralogy of the flake graphite ore in Heilongjiang province, mineral liberation analyser (MLA) was conducted to systematically study the mineral composition, particle size distribution, and dissemination characteristics of the ore based on the chemical analysis. The results showed that the percentage of the valuable element C existing in the form of graphite is 17.7% and the percentages of the primary gangue minerals feldspar and quartz are 34.32% and 20.83%, respectively. The percentage of large flake graphite whose grain size larger than 0.15mm is 46.17% and the liberation degree of graphite is 70% at 0.18mm

Key words: flake graphite; process mineralogy; mineral composition; particle size distribution; liberation degree; dissemination characteristics
