Abstract

Abstract

The structure of a certain graphite ore in Heilongjiang province belongs to gneiss type graphite ore, the gangue minerals are mainly quartz, feldspar and mica, and the metal minerals contain a small amount of limonite. The total fixed carbon content of the raw ore is 8.03%. The fixed carbon content of + 100 mesh large scale graphite in the raw ore accounts for 37.58% of the total fixed carbon content. After the process of one roughing, one scavenging and eight regrinding and eight cleaning, the fixed carbon grade of concentrate is 90.53% and the fixed carbon recovery rate of concentrate is 94.07%. Among them, the fixed carbon grade of + 0.15 mm concentrate is 95.26%, the fixed carbon recovery rate is 17.67%, and the protection rate of +0.15 mm large scale graphite is 47.02%.
