Abstract

High intensity magnetic separation of hematite ores is a wellknownbut an expensive method. In comparison with this traditionalmethod, magnetic concentration of magnetite ore formed after magneticroasting of hematite has been an alternative and reasonable process.Utilization of this process would be more economical than the traditionaltype and therefore, it has been preferred recently. In this process,the aim of the roasting is to increase the magnetic susceptibility ofhematite and thus make it recoverable by a low intensity magnetic separator.Divrigi Hematite ore having 47. 06% Fe of grade was recoveredwith an efficiency of 91.23% and the grade was increased to a level of62.26% Fe. Using the magnetic product obtained ill this process, pelletproduction suitable for the industry was achieved
