There are many stone coal vanadium extraction processes developed in recent years. Efforts to improve the extraction rate of vanadium and control pollutant emission have been paid more and more attention in the production process, and some new progress has been made in process improvement and pollutant treatment. Stone coal grinding mill equipment has been applied in many new processes. In some new processes of extracting vanadium from stone coal, stone coal mine grinding mill equipment is needed to grind stone coal mine into fine powder.
New technology of extracting vanadium from stone coal
The initial process of extracting vanadium from stone coal is sodium chloride roasting process (high sodium roasting), which has been eliminated due to the serious environmental pollution caused by HCl. In order to explore the vanadium extraction process with less environmental pollution, some relatively less polluted stone coal vanadium extraction processes have been developed in recent years.There are four new processes: (1) low sodium roasting and water leaching process; (2) Blank roasting (without salt) acid leaching process; (3) calcium salt roasting and acid leaching process; (4) direct dilute acid leaching process without roasting, etc. Among them, low sodium roasting water leaching process, blank roasting acid leaching process and direct dilute acid leaching process without roasting need to grind the stone coal grinding equipment to 150um-75um. The grinding process is conducive to more uniform and sufficient roasting and sufficient leaching.
