Abstract. Ausmelt has developed a process that allows the production of blister copper from copper concentrates, using either one or two furnaces depending on the scale of the operation. Ausmelts top submerged lance technology has been applied to numerous smelting processes including the recovery of most non-ferrous metals, and iron production. Based on its

Operation. Central to the Metso Outotec Ausmelt TSL process is the use of a vertically suspended lance submerged in the slag layer of the molten bath. Injection of fuel and process gases (air and oxygen) result in significant bath agitation and mixing, delivering a high-intensity, dynamic smelting process with highly specific smelting rates.
Ausmelt technology opens up new opportunities for the economic processing of complex copper smelter dusts. Not only can the technology separate more of the unwanted elements to produce a clean blister copper for refining, but it can also allow production of fume and precious metal products that can be readily upgraded to produce high-grade, valuable products.

Intensive smelting by the use of a top entry lance in a slag bath was developed by the CSIRO in Australia in the early 1970s. Key motivations in the early work were to recover values from slags and to smelt tin concentrates1. This work led to the granting of a patent to the CSIRO for the Sirosmelt Top Entry Submerged Lance (TSL) smelting system2. Dr. J. Floyd, who had headed

Apr 11, 2005 A large pilot plant was designed, built, commissioned, and operated for several months at Olympic Dam using 18 Ausmelts services. After production of the required range and tonnage of slags for the leaching trials, the matte produced, averaging approximately 70 pct Cu, was converted through to blister copper in the Ausmelt reactor.

The blister copper produced by this process is 99% pure copper. The name blister copper comes from the fact that this final process produces bubbles of sulfur dioxide on the surface of the copper. The blister copper is cast into anodes ready for electrolytic refining. The anode casting turntable moves slowly round.
