Review of Phosphorite Pre-treatment Methods for Furnace-process Phosphorus Production

Four methods for pre-treatment of phosphorite for furnace-process phosphorus production are described.The process features of the mainly sintering process and pellet induration's process currently used are compared.And it is proposed that pre-treatment methods for phosphorite are selected according to its property,and domestic yellow phosphorus producers should pay attention to the importance of phosphorite pre-treatment,so as to achieve reduction of energy consumption,stability of production,and full utilization of resources.
