Water is a vital resource on which many industries rely and which can be used more sparingly. An example is the beneficiation of mineral ores. Taking the raw material fluorite as their example, researchers at Helmholtz Institute Freiberg for Resource Technology (HIF) have now shown how water usage can be optimized. They have developed a new …
Traditionally, wet beneficiation technologies are widely used for coal cleaning, which consume a large amount of water [ 6 ]. However, water shortages are becoming a global problem. Thus, dry beneficiation methods have attracted increasing attention in recent years [ 7 ].
China's energy supply heavily relies on coal and China's coal resource and water resource has a reverse distribution. The problem of water shortages restricts the applications of wet coal beneficiation …

The Problem with Coarse and Fine Coal Beneficiation Economic and operating conditions make it important to provide a simple, low cost, efficient method for recovering fine coal from washery waste. Not only is the water pollution problem a serious one, but refuse storage and disposal in many areas is becoming limited and more …
For iron ore beneficiation, the separator provides a technology to reduce water usage, extend reserve life and / or recover and reprocess tailings. The compactness of the system allows for flexibility in installation designs.
Water is an essential resource for mining, beneficiation, and metallurgical operations. However, the industrial development has been a major contributor to the dilapidation of water quality, both through negligence in treatment of wastewater before discharge and accidental pollutant spills in an aquatic environment.
> Given South Africa's endowment of natural resources and its already established mining industry, there are a range of opportunities ranging from the development of resource deposits to manufacturing and beneficiation along the value chain.
The comparison of both the beneficiation methods for minerals indicates the more efficient recovery of potassium applying the chemical beneficiation method than the physical beneficiation method [ 31, 32 ]. The detailed discussion on the major potassium recovery process from different rocks and minerals is presented in Sect. 3.1.
The beneficiation process can be defined as a treatment process of ore which results in a more concentrated form of the product. It is often used in the preparation of iron ore for smelting. This is an essential process as it helps improve the yield from a deposit of ore, thereby increasing the potential profits that can be obtained from the ...
In addition, the ratio of IOT generated to utilized is high, due to the lack of advanced beneficiation techniques for low-grade ores in iron making process [22], and hence a large quantity of these tailings is still unused in the mining industry.
The beneficiation of the valuable minerals contained in fine particles is a complicated problem in mineral processing and particularly in gravity separation. The fines below 100 μm are generally discarded as gangue from gravity concentration processes which ultimately reports to tailing through process water stream.
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 …
In the case of dry dense medium processes, air/magnesite or air/sand suspension is utilized rather than water/magnesite or water/sand slurries, which are commonly used in conventional dense medium cleaning processes. Dry beneficiation techniques may be broadly classified as gravity-dependent or nongravity-dependent techniques.
