Graphite Ore Processing Flowchart
DETAILS
| Detailed Introduction
Process Introduction
Graphite is an excellent non-metallic mineral and an important raw material in industrial production. Due to its naturally floatable properties, flake graphite is primarily recovered through flotation processes in industrial applications.
Process flow
After the raw ore is crushed and ground, it undergoes flotation to produce a rough concentrate. The size of graphite flakes is one of its most important quality criteria; therefore, in the beneficiation of flake graphite, special attention must be paid to preserving large-flake graphite. Consequently, the rough concentrate typically goes through multiple stages of grinding and multiple stages of separation, ultimately yielding a refined product with a fixed carbon content ranging from 90% to 98%.
The R&D Center of Yantai Jinyuan Mining Machinery Co., Ltd. conducted beneficiation tests and research on various graphite ores in the Tanzania region. Under the condition that the raw ore had a fixed carbon content of 10% to 12%, the company achieved a graphite concentrate with a fixed carbon content of 97.5%, a recovery rate of 94%, and a fine particle recovery rate (+100 mesh) of 72%. These results represent excellent technical performance.
