Iron ore is a non-fungible commodity, and its quality varies. To help facilitate price adjustment for differences between expected and delivered product specifications, PRAs have developed value-in-use (VIU) indices for the key price-affecting chemical components of iron ore - iron, silica, alumina and phosphorus. Metal Bulletin’s VIU indices are calculated by analyzing price and,

Table-2: Choronological change of rates of royalty on iron ore (grade-wise) Year Grade Rate 1949 ore, containing 40% Fe or 1) For extraction of iron Annas* eight per tonne. 2) Other purposes Rs. 1/- per tonne 1962 1) 5% of the sale price

In Kirondul iron ore beneficiation plant, India, the iron ore fines are being beneficiated by grinding, hydrocycloning, spiralling and magnetic separation (HGMS) techniques to achieve the iron concentrate with 67% Fe for pellet feed. In Western Australia, Batac jig in combination with spirals are being employed for the beneficiation of iron ores. Table3. Chemical analysis of

Iron Ore. Efficiently remove silica and alumina contamination to increase efficiencies in steel production. Our iron ore wet processing plants are proven to successfully deal with silica and alumina contamination in the iron ore, resulting in an increase in the Fe value of the iron ore thereby increasing the efficiency of the steel production process.

29/03/2021· The current common iron ore blending methods only refer to the mixed ore indicators and the original ore’s nature, but ignore the impact of the mixed ore properties on the beneficiation production. They often regard ore blending and beneficiation as two separate processes, rather than using the former as an auxiliary link to the latter to ensure the quality of

15/05/2018· Capacity utilisation rates of domestic iron mines stood at 58.5% in July, down 1% from June. Concentrate output in domestic mines increased 333,000 mt from June to 21.7 million mt in July as the number of days in July was one day longer than that in June (3.3%).
