Removal of Phosphorus from High-Phosphorus

2019-12-16  High-phosphorus manganese ores provide an important source of manganese, which is regarded as an irreplaceable material in the steel industry. The ammonia-ammonium carbonate leaching method was proposed for the removal of phosphorus and extracting manganese from high-phosphorus manganese ore, both effectively and environmentally.

PHOSPHORUS REMOVAL FROM MANGANESE ORE BY

For the removal of phosphorus, the effects of argon gas flow rate, hydrogen gas content in the plasma gas, and plasma torch power were analyzed. In addition, based on the thermal decomposition of hematite in the ores into magnetite at a high temperature, a magnetic separation was conducted after plasma treatment aiming to upgrade manganese ores.
