The most important impurity is P (phosphorus) as a high level and the ore can't be smeltered by itself. If the P content is to high it has to mixed with a better Quality ore and high p levels make it hard to sell. High levels are considered above .85 and above. so Centrex levels are ok at .49. Also l don't see the Chinese companies reneging on ore contracts as they own 20% of the company. Why give your money to someone else when you can Garantee your own supply and make more money by increasing sp in your own company. The Chinese aren't stupid a lot of chinese companies are investing in Australian miners 1 to gurantee own supply if market supply tightens as by 2013 iron ore demands will have over doubled, and to make money again on there own demand.
