8 A manganese ore with a composition given below is reduced with carbon in orderto produce an alloy phase consisting of Fe,C and Mn,C only. An amount of CaOwhich is equal to the amount of SiO, present in the ore is added to the charge as afluxing agent. A part of manganese present in the ore is lost into the slag in theform of MnO which forms 10% of the slag phase. In order to produce 100 kg of alloyphase (Fe,C+ Mn,C), calculate:i. Amount of ore usedii. Amount of carbon usediii. Composition of the alloy producediv.

World production of chromite (FeCr₂O₄), the main ore ofchromium, was 1.5107metric tons in 2003. To isolate chro-mium, a mixture of chromite and sodium carbonate is heated inair to form sodium chromate, iron(III) oxide, and carbon diox-ide. The sodium chromate is dissolved in water, and this solutionis acidified with sulfuric acid to produce the less soluble sodiumdichromate. The sodium dichromate is filtered out and reduced with carbon to produce chromium(III) oxide, sodium carbonate,and carbon monoxide. The chromium(III) oxide is then reduced to chromium with aluminum metal. (a) Write balanced equations for each step. (b) What mass of chromium (in kg) could be pre-pared from the 2003 world production of chromite?
