Answer the following Name different zones in the Blast

c. Zone of slag formation (20 m height from the bottom) The gangue present in the ore is converted to slag. This slag can be used for making a road foundation. The temperature of this zone is 1200 K. The gangue contains silica, alumina, and phosphates. Removal of this gangue is effected by adding lime-stone in the charge, which acts as a flux.
