| Abstract: | The process and equipment of a 400 kt/a sulphuric acid plant based on pyrite in high-altitude region, Qinghai, are described. The operation situation and problems are analyzed. High-and low-level heat were recovered by waste heat boiler to produce steam for power generation. Cu, Co and Zn in slag were recycled. Produced iron concentrate was sold to steel plant. |
