WebThe chalcopyrite structure, which derives its name from copper pyrite (CuFeS2 ), is closely related to the zinc-blende structure. We consider it for two reasons. First, there have been many studies of materials with this or closely related structures. WebDuring roasting, copper pyrites are ultimately converted into a mixture of: A FeS+Cu 2S B FeS+Cu 2O C FeO+Cu 2S D FeS+Cu 2S→FeO+Cu 2O Hard Solution Verified by Toppr Correct option is D) Process: Copper pyrites contains only 2-3% of copper. The rest of ore contains iron as sulphide, silica, silicious materials, sulphur, arsenic etc as impurities. philosophical breakfast club

WebExpert Answer i) Chalcopyrite Chemical formula is CuFeS2 Dead roasting means , complete roasting , oxidizing the all sulfur present . Reaction involved in dead roasting … WebChalcopyrite, CuFeS 2, is an important source of copper. A typical chalcopyrite ore contains about 0.75% Cu. What volume of sulfur dioxide at 25°C and 1.00 atm pressure is produced when one boxcar load (4.00 × 10 3 ft 3) of chalcopyrite ore ( d = 2.6 g/cm 3) is roasted? WebThe weight composition of concentrate entering the furnace is CuFeS2 40%, Cu2S 4%, FeS 32%, SiO2 18%, CaO 3% and moisture 3%. Assuming 50% of the copper in chalcopyrite (CuFeS2) is oxidised to CuO and the balance copper exists as Cu2S in the roasted product. Assuming all the iron is oxidised to Fe2O3. philosophical buddhism
