Separation and recovery process of graphite carbon mud for artificial diamond production

The invention belongs to the technical field of artificial diamond production, and particularly relates to a separation and recovery process of graphite carbon mud for artificial diamond production. According to the separation and recovery process of the graphite carbon mud for artificial diamond production, the graphite carbon mud after diamond purification is subjected to crushing processing and particle size screening, the screened material is subjected to acid pickling purification by adopting a spherical electric heating reaction kettle electric heating process, and the dried graphite powder is subjected to high-temperature roasting treatment, and finally, graphite powder which is detected to be qualified is obtained. Cyclic utilization of graphite in the production process of the artificial diamond is achieved, so that the production cost is effectively reduced, and graphite resources are saved. The process provided by the invention realizes recycling of graphite, and the ash content, nitrogen and oxyge
