This work presents the results of carbonation experiments performed on Basic Oxygen Furnace (BOF) steel slag samples employing gas mixtures containing 40 and 10% CO2 vol. simulating the gaseous effluents of gasification and combustion processes respectively, as well as 100% CO2 for comparison purposes. Two routes were tested, the slurry-phase (L/S = 5 l/kg, T = 100°C and Ptot = 10 bar) and ...

SiroSmelt - CSIROpedia

In the years to 1980 there was gradual pilot-scale development of a range of slag-cleaning operations, and of smelting techniques for tin, copper, nickel, zinc and lead. In 1977 a permanent 100 kg/h pilot plant was established by the Smelting Research group at Mount Isa Mines for collaborative investigation of lead smelting (which was not permitted for safety reasons on the CSIRO site).
