Result of the tests led to the following Conclusions:
1. The Optimum Size was-35 mesh in electromagnetic separation of pyrrhotite ore but the undersize of 230 mesh must be removed by classifier before separation.
2. The Optimum size was-140 mesh in roasting of the ore.
3. The optimum temperature at-140 mesh are in roasting of pyrrhotite ore ranges from 600℃ to 700℃.
4. The optimum retaining time of the ore in roaster at-140 mesh ore was 40 minutes.
5. SO₂and O₂volume percentage in the gas would be from roaster 6% to 7% and 7% respectively.
6. The cinder will be able to use in the iron making by sintering.
