An iron ore was analyzed by dissolving a 1.3240-g sample in concentrated HCl. The resulting solution was diluted with water, and the iron(III) was precipitated as the hydrous oxide Fe2O3-XH2O by the addition of NH3. After filtration and washing, the residue was ignited at a high temperature to give 0.5394 g of pure Fe2O3 (159.70 g/mol).
India is likely to export about 20 million tonnes of iron ore in 2022/23, down from 26.3 million last year, the officials said, with China still the biggest buyer by far.
