Method for removing phosphorus from phosphorus containing material, method for producing metal smelting raw material or raw material for metal refining and method for producing metal

摘要

In order to effectively reduce phosphorus contained in the phosphorus containing material, which is a solid oxide used as the main raw material or secondary raw material for metal smelting or metal refining, the method of removing phosphorus from the phosphorus containing material, which can be applied in an industrial scale, is Manufacturing method of metal and refining raw material and manufacturing method of metal are proposed.A phosphorus containing material used as a material for metal and refining is reacted with nitrogen containing gasA method for nitridation of phosphorus in said phosphorus containing materialPrior to nitridation of phosphorus from the phosphorus containing substance, prior to the treatment of phosphorus removalThe phosphorus containing material is heated to an unmelted temperature range to react with the reducing agent.A method for removing phosphorus from a phosphorus containing material that carries out a process for reducing at least a portion of a metal oxide in the phosphorus containing materialMetal and refining materials and methods for producing metal using this.
