This was the entire point behind the POSCO type furnaces. They are modern and can take the lower metal content ores India produces. This way we can avoid the present situation where India exports low quality ore at cheap price and imports high quality ore at inflated price. Even POSCO has said it will have to import higher quality ore to mix with lower Indian quality ore. To offset this import cost POSCO planned to export some Indian ore so they can hedge prices. There was a big uproar on this very board about that export business some time back. As it is when POSCO comes on line expect iron ore imports to skyrocket.
Indian ore is generally of good quality. The ones that get exported from Goa, karnataka etc are generally lower quality with lower iron content. The best ores in India are used domestically probably with the exception of the Bailadilla Mines output of Dantewada exported via Vizag.
POSCO set off an uproar because it wanted a huge iron ore allocation ,way beyond what the Indian operations would use , to be able to export iron ore back to Korea. It was a round about way to get high quality ore, while at the same time getting a foot hold in the Indian market. A killing two birds with one stone thing.
Oh, it is not as if the iron ore fines/etc are useless. It needs a sintering and /or pelletizing plant anyways before being used in a blast furnace.
What the Corex process like the Jindal Vijaynagar /JSW steel plant does is that it does away with the coke oven batteries (they make coke from coal) and the Corex gas can be used to generate power. In fact JSW has one of the largest corex capacities in the world (nearly twice Posco's) I think. Posco doesn't bring anything new to the table, in terms of technology or anything (all steel making technology is from major vendors), just investments, which is welcome of course. But other than that, no great shakes.
