Introduction about Graphite Beneficiation Process
Crystalline graphite has natural floatability, so Hongji mainly uses flotation method to separate graphite ore. Flake graphite has good floatability, so it is mostly separated by flotation method. For graphite ore with a variety of gangue, the combined process of gravity separation and flotation can also be used.
Process of Graphite Beneficiation Process
Multi-stage grinding and multi-stage flotation
In order to protect graphite flake from damage, Hongji often adopts a multi-stage grinding selection process. The quality of the concentrate can meet the requirement after several regrinding and resorting.
Combined gravity separation and flotation process
For graphite ores accompanied by heavy minerals, Hongji's combined gravity separation and flotation process can be used for sorting, that is, the heavy minerals are first separated by gravity separation, and then the heavy separation tailings (light minerals) are treated by flotation.
Flotation reagent
In the multi-stage flotation process, the commonly used foaming agents are No. 2 oil, No. 4 oil, ether alcohol, butyl ether oil, etc. The collector is kerosene, diesel oil, heavy oil, sulfonate, sfate, phenols, carboxylic acids, etc
