A blast furnace makes pig iron containing 3 . 2 % and 1 . 8 % of Carbon and Silicon and remaining as Iron respectively.

A blast furnace makes pig iron containing 3.2% and 1.8% of Carbon and Silicon and remaining as Iron respectively. The ore is a combination of 80%,12% and 8% of Iron Oxide, Silica and Aluminum Oxide respectively. The process requires coke at a rate of 1Kg per kg of pig iron produced. The coke is adulterated with Silica with 10% of silica and remaining to be carbon. The flux is obtained at a rate of 0.4kg per kg of pig iron and is containing pure Calcium carbonate. The blast furnace gas has 30%CO and 15%CO2. Considering the base of one tonne of pig iron produced, calculate the following assuming the necessary data required:
[15]
The weight of core used.
The weight of slag made.
The volume of the blast-furnace gas.
