Ore Smelter Plant Slag Granulation Price. 86 IRON AND STEEL SLAG. Actual prices per ton ranged in 2019 from a few cents for some steel slags at a few locations to about $120 or more for some GGBFS. Owing to low unit values, most slag types can be shipped only short distances by truck, but rail and waterborne transportation allow for greater ...
A granulation pilot plant was installed at Algoma Steel Corp., Sault Ste. Marie, Ontario, for the production of about 40 metric tons of granulated blast furnace slag to be tested for concrete and mine backfill applications. The granulated slag was obtained by quenching the molten slag by jets of high-pressure water.
