Question: For the following process, draw the materials flow diagram, write the independent reactions, do the degree of freedom analysis and complete the materials and energy

For the following process, draw the materials flow diagram, write the independent reactions, do the degree of freedom analysis and complete the materials and energy balances

Calculate the material and energy balance for the reduction of a chromium ore to produce 1 ton of ferro-chromium using an ore with the analysis 54% Cr2O3, 15.5% FeO, 13.5% MgO, 10% Al2O3, 7% SiO2. Quartz (97% SiO2, 3% gangue) is used as flux and 25% excess coke with the analysis 87% C. Carbon in coke is also used to reduce the oxides in the ore (Cr2O3, SiO2 and FeO). Assume there is 7% C in alloy, 1.5% Si in alloy (reduced by C), and 30% SiO2 in slag.
