However, the recovery ratio of this substantial highgrade thermal energy was quite limited due to the immature technologies (Sun et al., 2015a, Zhang et al., 2013) and thus there was a great potential to recover the waste heat from the high temperature steel slags.

(5) The thermal energy of high temperature slag is wasted without recovery. To solve these problems, we studied the dry granulation of the molten slag by rotary cup atomizer (RCA). The molten slag was supplied to the center of RCA. The rotating cup forces the slag outward to the cup lip where it is granulated with blasting.

2. Viscosity of liquid slag which becomes high with low FeO content blowing of oxygen helps in improving the separation of P205 from slag. 3. Size of crucible, the more is the depth better is the separation 4. Slag composition which determines the viscosity, the lower is the basicity clearer the separation. Fluorspar helps in improving the fluidity 5.
