processed for coppercobalt recovery to produce a coppercobaltiron alloy in the cobalt recovery furnace (CRF). The CRF process aims to obtain a final slag of approximately % copper and % cobalt which is normally discarded. The reductant used in these two processes is coke. The CRF process is intended to maximize the recovery of copper and
ISASMELT technology has been applied to lead, copper, and nickel smelting, and by 2013 fifteen plants were in operation in ten countries, with another five in various stages of development. The installed capacity of the operating plants in 2013 was over 8 million tonnes per year (t/y) of feed materials, with additional capacity to come on line in 2013 and 2014.
Copper smelting slag is produced from copper pyrometallurgy (both smelting and converting stages), usually grading at %. The slag may also contains lead zinc minerals like galena, sphalerite. Copper mainly dwells in the slag in the form of bornite, chalcocite, chalcopyrite, and metallic copper.
The recovery of copper from reverberatory furnace slag utilizing flotation has been studied. The effective factors such as particle size, pH, the amount and type of collector and additives, and flotation time were examined. The effect of cooling rate on flotation behavior of the slag was also studied.
Outotec Slag Cleaning Slag cleaning at copper and nickel smelters is typically done using an electric furnace process. The design of Outotec slag cleaning furnaces is based on our extensive experience with different slag compositions and understanding of how to optimize the process for maximum recovery.

Slag produced by flash furnace operations contains significantly higher amounts of copper than reverberatory or electric furnaces. Flash furnace slag is treated in a slag cleaning furnace with coke or iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide.

MANAGEMENT OF COPPER PYROMETALLURGICAL SLAGS 543 Introduction During the last years, due to worldwide economic recession and a large inventory of stock, copper reached a historical value of US/pound in 2001. This fact meant closing down many important mining companies in the world, mainly in USA. On the other hand, strong
All these three furnaces produce fayalite slag as a byproduct. The slags contain copper with the content ranging between to 5% copper. The slags cannot be discarded due to the high content of copper and hence they are sent to a milling and flotation plant (Slag Mill Plant) for liberation and recovery of copper.
Additional silica is normally added to help form the slag. The furnace is fired with burners using pulverized coal, fuel oil or natural gas and the solid charge is melted. Reverberatory furnaces can additionally be fed with molten slag from the later converting stage to recover the contained copper and other materials with a high copper content.
