A copper matte which is composed of liquid FeS and Cu2S is charged to a converter during copper smelting operations. The matte contains 54wt%Cu2S and is balanced with FeS. During processing air is blown through the matte, oxidizing FeS according to the stoichiometry: 2FeS+3O2=2FeO+2SO2 Operators of the furnace need an estimate of what will happen during the reduction. They are currently charging 40,000kg of matte to the system. In order to provide this information, you must calculate the following: a) The total volume of air necessary (written in Nm3) b) The total volume of SO2 produced (written in Nm3 ) c) The weight of FeO produced (written in kilograms) d) The weight of slag formed, assuming that silica flux will be added as necessary to attain a weight ratio of 65wt%FeO to 35wt%SiO2 (written in kilograms)
