Process of red mud using microwave assisted selective extraction and carbonation using leachate and Fe magnetic separation from residue

摘要

The present invention relates to a method of treating red mud, comprising the step of irradiating a red mud with microwaves and a step of filtering the mixture of red mud and distilled water to separate an extract and a precipitate, Can be recovered as carbonate minerals, and the precipitate can be used for recycling the red mud by magnetically separating and recovering iron.
