2021.8.3 The yellow phosphorus production by electric-furnace method has always been the core of thermal process for phosphate rock treatment. The electric-furnace method should be able to make direct use of the low-grade phosphate rocks, especially those with high silicon content, but this would consume a lot of energy.

Renewable energy for production of elemental phosphorus
Elemental phosphorus is produced by an energy-intensive process that involves smelting phosphate ore in submerged-arc electric furnaces. Approximately equal quantities of energy are supplied as electricity and reducing carbon. The phosphorus industry is offered a new process to reduce the overall energy requirement about 40%.
