Technical progress in comprehensive utilization of pyrite cinder at home and abroad is introduced. According to research and practice,ore concentration is superior to cinder concentration both technologically and economically.Several key problems with ore concentration are analyzed such as dressing process,target grade of pyrite concentrate,sulphur recovery and tailings treatment.Recovery of valuable metals and iron pellet making by pyrite cinder are discussed.It is pointed out that ore concentration for recovering iron form cinder should be popularized in the industry.
