Abstract Ausmelt Top Submerged Lance (TSL) Technology has demonstrated its ability to adapt to new ap-plications and feed types from an established base for producing a range of non-ferrous metals.. In copper alone, the technology spans a range of processes from primary smelting through Continuous Copper Converting (C3) and the ability to treat the …
Smelting Mechanisms Ausmelt/Isasmelt smelting is different from flash smelting in that the smelting reactions take place primarily in the bath rather than above the melt. As a result, the reaction sequence is different. It is commonly believed that dissolved magnetite in the slag serves as a catalyst of sorts for the overall process.
