mass balance problem
An ironmaking blast furnace produces hot metal of the composition: , . The composition of the iron ore is moisture. Coke rate is . Composition of the coke is . Enough limestone is charged to make in slag and composition of limestone is . Calculate (i) Weight of ore used per tonne of hot metal production; (ii) weight of slag produced per tonne of H.M.; (iii) weight of limestone used to produce given slag composition.
Expert Answer
To calculate the required values, we need to use the given information and perform some calculations. Let's go step by step:(i) Weight of ore used per tonne of hot metal production: First, we need to determine the amount of iron (Fe) in the hot metal and the amount of iron in the iron ore. Then we can calculate the weight of the ore used.Given: Composition of hot metal: 93.6% Fe Composition of iron ore: 78% Fe2O31. Calculate the amount of iron in the hot metal: 2. Calculate the amount of iron in the iron ore: 3. Equate the iron in hot metal to the iron in the iron ore and solve for the weight of iron ore:
