Processing of Goethitic Iron Ore Fines SpringerLink
In the present investigation an attempt has been made to beneficiate goethitic iron ore containing 59.02 % Iron, 6.51 % Alumina, 4.79 % Silica, 0.089 % Phosphorus with 7.11 % loss on ignition. For this purpose, different beneficiation techniques such as gravity and magnetic separation processes have been employed. During the Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue. The latter can be suspended in a stream of water and flushed away. The iron ore magnetite, Fe 3 O 4, is ferrimagnetic. It can be separated from abundant deposits of taconite by grinding to a22.4: Beneficiation Chemistry LibreTexts

Introduction: Overview of the global iron ore industry
Turning to iron ore exports and imports, the tonnages are summarized in Table 1.1 for 2012 and 2018 (Australian Department of Industry, Science, Energy and Resources, 2021; US Geological Survey, 2020; United National Conference on Trade and Development (UNCTAD), 2021).As shown in Fig. 1.3, China is the largest iron ore The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the high-grade ores depleting very fast, the focus is on the beneficiation of low-grade resources. However, most of these ores do not respond well to the conventional Existing and New Processes for Beneficiation of Indian Iron

Bauxite Beneficiation: An Approach to Value Addition in
The primary objective of beneficiation for non-metallurgical bauxite is to lower iron and titanium contents in the product, and also to enhance alumina values. This often requires more complicated processes, such as the use of a high-intensity wet magnetic separator, with fine grinding of bauxite to liberate the iron minerals.Aluminum industries use bauxite as the major raw material . Bauxite containing less than 50% Al 2 O 3 is called low-grade bauxite ore, which is generally used for the production of aluminum appliances such as abrasives, ceramics, and refractories . The presence of impurities, including silica, iron oxides, and calcium contribute to the Advances in Beneficiation of Low-Grade Bauxite SpringerLink
