The ore mainly consists of quartz and graphite assaying 87.80% ash and 8.59% fixed carbon. It was crushed in stages followed by primary coarse wet grinding. Rougher flotation was carried out in conventional flotation cell to eliminate the gangue to the maximum extent possible as primary tailings.
And froth flotation process is the main graphite ore processing method. Generally, 90% 97% grade of graphite concentrate can be obtained after the graphite flotation process. For the different graphite ore properties, the graphite mining processes are also different.
Comparison of flotation performance between the flotation column and mechanical flotation was carried out to promote the grade and economic value of the graphite ore . The ash content of the concentrate of the mechanical flotation was 10.77% at the yield of 79.34%.
While other materials include soya beans oil, kerosene and graphite ore. METHOD A sample of ground graphite was weighed up to 300g using the triple beam balance. Distilled water of up to 1000cm3 was measured and mixed with the graphite ore, poured into the flotation cell and agitated for 2 minutes at the speed of 1500rpm.
The graphite ore beneficiation process is mainly for the graphite ore with different crystal forms, such as graphite ore, pyrite or mica. It adopts multi stage grinding multi stage flotation and re election flotation combined with two beneficiation processes.
Froth flotation is commonly used for the concentration of low grade graphite ore. There are mainly there beneficiation method to extracted the high grade graphite including mechanical flotation cell, column cell and bulk oil flotation. Three Graphite Beneficiation Methods cell flotation of graphite
Graphite ore flotation process is an efficient graphite ore deep processing technology, it can greatly increase the application of graphite ore area, selected graphite ore concentrate, can meet the diverse needs of various fields of production.
