The focus of the mining industry is shifting towards potential new resources in remote areas as a result of decreasing ore grades. Remote sensing technology is an effective and widely established analytical method for geology and mineral exploration and has proven extremely beneficial by providing access to dangerous or previously inaccessible mineral deposits.
Aug 27, 2019· Tilden operations consist of an open pit truck and shovel mine, a concentrator that utilizes single stage crushing, AG mills, magnetite separation and floatation to produce hematite and magnetic concentrates that are then supplied to the on-site pellet plant.
Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3).. Iron ore is the source of primary iron for the world's iron and steel industries.
Jun 29, 2020· Our Iron Valley site, located within the Pilbara, is currently our largest iron ore producing mine, outputting approximately 8 million tonnes of iron ore per annum. Product from this mine is transported to Utah Point for export to our global markets. In 2018, we acquired the Kumina Iron Ore Project from BCI Minerals Limited.
Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
