Question A copper ore containing 20% Cu,S, 40% FeS2, 30% SiO2 and 10% H,O is roasted byusing fuel oil whose weight is equal to 5% of the ore weight. Exhaust gases fomed as a result of combustion flue gases. Sulfur is exhausted as sulfur dioxide and discharged as flue gases. The products of roasting reaction are CuO, Fe,O; ve SiO2. Roasting and combustion reactions are realized using 100% excess air. The fuel contains 85% C and 15% H. process are mixed with the product gas of the roasting reaction and discharged as a. Determine the amount of the air (m³) used per 1 tonne ore. b. Determine the weight of the roasted ore. c. How many grams of H,O is found in flue gases per m².

A copper ore containing 20% Cu2S, 40% FeS2, 30% SiO2 and 10% H>O is roasted byusing fuel
oil whose weight is equal to 5% of the ore weight. Exhaust gases formed as a result of
combustion process are mixed with the product gas of the roasting reaction and discharged as
flue gases. Sulfur is exhausted as sulfur dioxide and discharged as flue gases. The products of
roasting reaction are CuO, Fe,O; ve SiO2. Roasting and combustion reactions are realized using
100% excess air. The fuel contains 85% C and 15% H.
a. Determine the amount of the air (m³) used per 1 tonne ore.
b. Determine the weight of the roasted ore.
c. How many grams of H2O is found in flue gases per m³.
