| Abstract: | The raw material of pyrite calcined cinder from some vitriol plant was researched with the test flowsheet of water-mill-magnetic and separation-flotation.After grinding the calcined cinder containing 42.4% and sulfur containing 1.37% followed by magnetic separation-flotation-chemical marinating,the iron concentrate having a grade of 63.6% and sulfur containing 0.12% could be obtained.The product can be used as the raw material of third class puddling. |
