Abstract
After smelting the copper ores in flame furnace crated matte that is smelting Cu2S and FeS. The amount of copper in Matte determined amount of Cu2S while rest is while FeS. In reallity matte contains less sulfur and other metals such as: PbS, ZnS, Fe3O4 and noble metals but their amount is small and does not affect the calculation. Processes of smelting in furnace and also in the converter is conditional on the fact that sulfur (S) is greater affinity to copper (Cu) than to iron (Fe). The percentage of copper in Matte depends on the amount of sulfur in cargo. Copper associated with assigned amount of sulfur and forms Cu2S while the rest non-oxidized sulfur forms FeS. It follows that, much more have sulfur much more will be formed with FeS with that reduced the amount of copper in Matte. The amount of sulfur to oxidize the whole amount of sulfur in cargo ranges from 13-30% and passes in the form of SO2 in gases. From the amount of iron in cargo an part passes Matte in form of FeS while the rest in slag in form of FeO. Losses of copper in slag are less than 0.9% of the amount of slag that with more precise definition of cargo and control of technological parameters of the process can be reduced.
