The beneficiation of kyanite ores by a new dry technology is studied. Compared to the flotation method, the method reduces energy consumption from 300 – 400 to 15 – 25 kWh/ton. Dry electroseparation has made it possible to obtain concentrates with an Al2O3 content of 59 – 60% while also producing pure quartz ("tailings").

The ore was crushed in stages followed …
Rare-earth elements (REEs) are required for use in modern high-tech applications and demand has increased significantly over the last decade. 1 However, processing of REE ores poses potential hazards to human health and the environment due to challenges in the management of thorium (Th) and uranium (U) in waste products. 2 If …
Fig 3 Types of processing ores. The wet processing (Fig 4) is normally practiced for low / medium grade (60 % Fe to 63 % Fe) hematite iron ore. The wet process consists of multi-stage crushing followed by different stages of washing in the form of scrubbing and / or screening, and classification etc., but the advantage is only partial …
The beneficiation process aims to increase the iron content and reduce impurities in the ore, resulting in a higher-quality concentrate suitable for further processing and utilization. The specific beneficiation method employed depends on factors such as the mineralogy of the ore, the presence of specific impurities, and the desired iron content.
The global market has announced copper as a modern energy metal and finds its extensive utilization in the construction industry, electrical wiring, power transmission lines, alloying, anticorrosive coating, heat exchangers, refrigeration tubing, etc. Copper ore is primarily beneficiated from sulphide mineral deposits. Due to high-grade …

This paper addresses the need for investments in ore beneficiation and scrap upgrading in the decades to come in order to meet demands on mitigating emissions of greenhouse gases as discussed at the AIST Scrap Supplements and Alternative Ironmaking 8, Orlando 2020 (Gyllenram et al. 2020).The theme of the …
Graphite is an important industrial mineral. Two types occur in nature, crystalline and amorphus. Crystalline graphite is used principally for crucibles and shaped structures. Amorphus graphite is used extensively in the steel and lubrication industries. In many deposits the two types grade into each other and the ore is of such low grade that …
ABSTRACT Graphite as the most common polymorph of naturally occurring crystalline carbon is required for many different applications such as batteries, refractories, electrical products, and pencils. Graphite resources are currently being subjected to intensive exploration to help meet rapidly growing global demand – and graphite has …
As the high value and the scarcity of large-flake graphite ore resources, it is in the best interest to maximize the amount of large flakes and minimize any processing that will reduce flake sizes. In the study, the mineralogy of an African graphite ore was estimated using X-ray diffraction (XRD), X-ray fluorescence (XRF), and optical …
The organic component of graphite is a relatively weak absorber of microwave energy (Menéndez et al. 2010, 2011), whereas some minerals (such as pyrite) and water in their structures readily heat within an applied electric field. ... graphite product quality while containing beneficiation process costs. Size of graphite particles as an ...
Keeping the above characteristics in view, several west coast lateritic bauxite mines of India employ dry crushing−screening process to bring down silica content from the metallurgical grade bauxite [].Recently, a bauxite mine of Guinea known as AGB2A has also adopted the dry beneficiation procedure to cut down silica from about 7% to below …
Following the mineral processing beneficiation of a natural graphite mined ore to make a graphite concentrate, further purification can be done by chemical leaching. In conjunction with caustic and hydrochloric (HCl) leaching, hydrofluoric (HF) acid can be used for its ability to leach both the metallic impurities and the silica (quartz ...
In particular for graphite beneficiation, a multistage grinding and flotation process (can be up to 10 or more stages) is commonly employed (Peng et al., 2017, Peng et al., 2023). The main purpose of this strategy is to progressively liberate and remove the gangues from graphite concentrates, thereby minimizing the detrimental damage to ...
