Abstract

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
