Pyrite roasting, an alternative to J sulphur burning
Pyrite roasting, an altenative to sulphur burning. Pyrite grain size is usually up to 6 mm in diameter. The coarser the grain, the higher the gas velocity must be to maintain the bed in a fluidized state. Even flotation pyrites with a grain size less than 70 μm can be processed in the fluid bed roaster.
