Ausmelt process

The Ausmelt process to treat Browns concentrates is designed to maximise the deportment of cobalt and lead to the matte and fume phases respectively. To ensure high cobalt recoveries to matte the Ausmelt furnace is operated under reducing conditions at 1300oC to produce a slag containing less than

    Ausmelt / Isasmelt Matte Smelting: Part One :: Total

    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

    process conditions can be generated in the furnace, from highly reducing right through to highly oxidising. These characteristics are quite different from those of alternative high intensity techniques which utilise suspension smelting. There are three main reasons why Ausmelt is often the selected technology when smelters expand
