Using the pilot plant fluidizing roaster, the pressure drop through the bed and the variation of its size distribution with the amount of overflow cinder were measured. The results obtained were as follows:
(1) The pressure drop obtained from the bed of particles under the conditions of roasting operation was closely approximate to the value by the Parent's equation which stated that the pressure drop was equivalent to the weight of sample.(2) From the experiments of varying amounts of the overflow cinders, it was found that the fraction of coarse particles tended to increase with decrease of the amount of the overflow cinder.
Then, the operation and its conditions of the pilot plant fluidizing roaster in the selective chlorination roasting of pyrite cinders were described in detail.
