  • Control of Copper Smelter Fugitive Emissions

    The copper content of the slag is maintained at 05 to 06 percent Cu by maintaining a reducing atmosphere in the slag cleaning furnace The slag then flows by gravity to the converter furnace The converter furnace produces anode copper which flows to a holding furnace prior to anode casting Slag from the con verter furnace is granulated Nickelcopper furnace and converter slag 200 kVA During 1995, a campaign was undertaken on the 200 kVA furnace with the intention of combining furnace slag with the converter slag previously treated When treating furnace slag containing 022% Co on its own, the maximum cobalt recovery that could be obtained was 66%, with a cobalt value of 0 Recovery of cobalt, nickel, and copper from slags, using copper content in the ore of copper deposits, which are nowadays in exploitation Slags, obtained by metallurgical treatment of copper, usually with different methods of preparation and concentration, are treated for recovery of copper Smelter slag of reverberatory furnace is obtained in the process of metallurgical conCOMPARATIVE RESULTS OF COPPER FLOTATION FROM

  • Minimization of Copper Losses in Copper Smelting Slag

    For these conditions, the copper losses in the slag are roughly 75% as dissolved copper and 25% as entrained matte and copper Such conditions include operating the electric furnace at metallic copper saturation, maintaining the %Fe in the electric furnace matte between 6 wt% and 9 wt%, not exceeding a slag temperature of 1250°C, and copper is recovered from coppercontaining slag by putting the matte and slag in a molten state together in a slag treating furnace at a volume ration of more than 1:5, the melts in the furnace being maintained under agitation so that the slag and matte are in intimate contact so as to efficiently transfer copper from the slag to the matteUSA Method of recovering copper from slag Separating copper and arsenic has always been a major problem in the copper slag flotation process, which influences copper slag utilization and the environmental safety A comparative study of flash smelting furnace (FSF) slag and its flotation products (concentrate and tailing) reveals the factors Mineralogical and morphological factors affecting the
