With approximately US$21bn dedicated to mine, port and railway expansion programmes to boost its Australian capacity, we expect Rio Tinto to stay at the bottom of the global cost curve due to its efficient and well-developed infrastructure. Iron ore is a bulk .
Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high quality fine .
Iron constitutes about five per cent of the Earth's crust and is the fourth most abundant element in the crust. Australia is one of the world's major iron ore producers.
