Iron ore In the 80s

"This paper will identify where the industry is heading with iron· ore in the next ten years. From a customer's point of view, an indication of the changing, yet expanding, market will be made. This will progress further into the most likely changes in chemical and physical requirements of the ore products. No definite target can be set for 1990, but the logic from the direction of the changes will be established.IntroductionThe tonnage and quality of iron ore produced in the eighties will be heavily influenced by energy and investment considerations. That's not a great pronouncement, but this paper will explain how these two factors are :(I) influencing a disproportionate growth of electric furnace capacity and a greater use of scrap for iron units, in place of Iron ore;(2) influencing chemistry specifications; and(3) causing extensive examination of ore agglomerate form. Inflating investment costs are emphasizing the need for more productive blast furnaces, and the iron ore burden is under heavy examination as to how it affects productivity and coke rate."
