Iron ore is an important raw material for steel production enterprises. In most cases, iron ore with a grade of less than 50% requires ore beneficiation before smelting and utilization. Natural ore (iron ore) is gradually selected for iron through procedures such as crushing, grinding, magnetic separation, flotation, and gravity separation.

Increased mining activity of iron ore has led to the generation of voluminous wastes of various nature, especially during the different stages of its extraction and production. The improper disposal of such waste causes negative impact on the environment. One such waste which is generated during the beneficiation process of iron ore is waste iron ore tailings, which is also termed as IOT.

The haematite ore in South Africa is processed in a dry process to a HQ lump ore with 64 % iron content and a sintered fine ore with % iron content. For fine ore beneficiation, wet processes are used. Capacity at the Minas Rio is to be increased from Mta capacity to 28 Mta in the forthcoming years.
Turning to iron ore exports and imports, the tonnages are summarized in Table 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., China is the largest iron ore importing country and imported about 69% of the world's seaborne iron ore ...
Much of the remaining iron ore resources in Brazil consist of lowgrade itabirite ores. Accordingly, a typical beneficiation circuit includes a fourstaged crushing/screening plant, followed by grinding in a closedcircuit ball mill, desliming in hydrocyclones and final ore mineral concentration via multistage reverse flotation and thickening of the final product.
The beneficiation techniques such as scrubbing, classification, gravity separation, magnetic separation and flotation are generally utilized to enhance the quality of the iron ores. In India, beneficiation is carried out by washing, jigging or classification techniques.

Beneficiation is the process where ore is reduced in size and gange separated from the ore. Since all iron ore deposits have unique mineralogy, the beneficiation process is specific to each deposit. Separation of certain minerals can be efficiently achieved by taking advantage of the physical, electrical and magnetic properties.

: Beneficiation. Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. 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 processes of removing highly dispersed suspended solids from process water during the iron ore beneficiation were studied in [6]. The disadvantage of this approach is the use of chemical action on the processes of thickening and desliming, which complicates the operational control of the processes.
