Changing dynamics of iron ore pellets industry

Sep 12, 2018The total iron ore pellets demand was ~443 Mt in 2017, which is expected to grow at a CAGR of 6% to ~529 Mt by 2020. The growth in the iron ore pellet demand is expected to lead to a strong growth in the demand for both BF and DR pellets. This phenomenon will certainly benefit countries which have large capacities of iron ore pellets such as

At low driving rates, the lowest coke rates were obtained with burdens composed of fluxed sinter. At higher driving rates, however, good pellet burdens gave the better coke rate and the higher productivity. Nevertheless, the tests run with a sinter burden at high driving rate should be repeated, as the sinter contained a higher percentage of fines (0-3/16 in.) than during the first test.
