Finally,the most reasonable technological process of“stagewise grinding,coarse and fine classification,gravity separation magnetic separation reverse anionic flotation”has been found out.
By technique checking every operations of recovery circuit,calculating the classification of spitzkasten and cyclone,thickening efficiency,assaying the ash of every operations.
Three technology options including precombusfion capture,oxyen-fired combustion and postcombustion capture and their process flows for capturing CO2 are introduced in this paper.
