Top Submerged Lancing Technology (Sirosmelt) for Achieving Difficult Separations in Smelting Complex Materials

The Sirosmelt top entry submerged lance system is a versatile bath smelting system which will treat many types of feed material. Of particular interest to the metallurgical industry is the system’s ability to treat complex, multi-component materials, such as zinc leach residues, complex Pb-Zn-Ag ores, and Due dusts. Operations at the Ausmelt pilot plant facilities in Victoria, Australia have shown that these materials can be treated to recover the metal values, and to produce environmentally acceptable slag; which can be cither dumped or sold as road or cement making material. The Sirosmelt process provices industry with a low cost (both capital and operating) unit which allows the treatment of the dumps of material present at some sites.
