Abstract:

South Africa (SA) joined BRICS in 2010. The study explores the impact of its partnership with the BRICS group on mineral beneficiation in South Africa (SA) from its inception. The BRICS association, that had originally sought to deal with economic issues the founding members faced, became a full-fledged “umbrella organization”, which factors into its engagements a variety of issues including those of policy and polity, economy and culture and certainly the relations between the member countries. The study culminates in designing a Mineral Beneficiation Model proposed to South Africa with the a

India is well-known for its rich deposits of high-quality hematite ores, making it a vital player in the global market. As the availability of high-grade iron ores diminishes, the need to process low-grade ores, fines and slimes through beneficiation is becoming increasingly important to meet market requirements. The creation of fines and slimes leads to a mineral loss of about 20 to 25% of the overall mineral value during processing.

Abstract:

The characteristics of Baiyun Obo niobium-bearing minerals are complex physicochemical properties that make the beneficiation of niobium minerals extremely difficult. In this paper, X-ray diffraction, X-ray fluorescence and mineral liberation analyzer (MLA) systems were used to study the niobium occurrence state and distribution of niobium-bearing minerals in the samples from Baiyun Obo. The results show that the chemical and mineral compositions of the sample are complex, with a Nb2O5 grading of 0.24%. There are many kinds of niobium minerals, including ilmenorutile, nioboaeschynite-Nd, baoti

Abstract Automatic process mineralogy detection system has been widely used in beneficiation process parameters detection, cause finding, and defect diagnosis in concentrators. A gold ore composition in Shandong is more complex, and recovery is difficult. To clarify the ore properties, mineral composition, main minerals, embedded characteristics, and monomer dissociation characteristics, the scanning electron microscope, BPMA, and energy spectrometer are used for the ore sample process mineralogy research to provide a reliable basis for the study of the selection process.

Abstract:

The paper recovered the Fe and Mn minerals from a refractory ore in Yunnan province. The grade of Fe in raw ore is 30.16% and the grade of Mn in raw ore is 20.05%. Through technological mineralogy study, we found the Fe was mainly in the forms of Hematite and limonite, and the Mn was mainly in the forms of pyrolusite and psilomelane. Through the process of strong magnetic separation, re-grinding and magnetic separation, the minerals of Fe and Mn were recovered, and the Fe mineral was separated from mixed concentrate successfully. Finally, we got two products. They were Fe concentrate with the

Geometallurgy is an interdisciplinary research field concerned with the planning, monitoring, and optimisation of mineral resource extraction and beneficiation. Geometallurgy relies on a quantitative understanding of primary resource characteristics such as mineralogical composition and texture, the spatial distribution and variability of these characteristics, and how they interact with mining and beneficiation processes. Thus, geometallurgy requires accurate analytical data for resource characterisation and detailed models of orebody geology, mining and processing technologies, mineral econo

The rising resource demands in emerging economies have intensified resource nationalism in mineral-rich countries, necessitating more efficient mineral processing technologies for declining ore grades. This study presents BGF-YOLO, a novel deep learning model enhanced from YOLOv8, designed to optimize mineral beneficiation by accurately identifying mineral species and grain sizes using hyperspectral imaging. The system utilizes hyperspectral data spanning 66 spectral bands (4001000 nm) and processes large datasets through advanced feature fusion and attention mechanisms. BGF-YOLO integrates a

Abstract:

The current centrifugal concentrators do not continuously concentrate heavy minerals of large mass weight—for example, in the processing of iron oxides. A cyclone centrifugal separator is a new type of beneficiation equipment that has been developed on the basis of the principles of centrifugal separation and hydrocyclones. In this study, a cyclone centrifugal separator was used for the beneficiation of a hematite–quartz mixture, and the separation effect under different operating conditions was analyzed. The results showed that various factors, such as the feeding concentration, the feeding p

Abstract:

Value created by mineral beneficiation processes relies on physical separation (including flotation) of particles containing different grades of metals or minerals of economic interest. The value created is a direct consequence of exploiting heterogeneity as governed by the properties of the natural resource that is processed, most often starting by well-controlled size reduction processes, e.g. blasting, crushing and grinding. These are usually applied in a stepwise fashion before the separation stage exploiting the liberated mineral(s) of economic interest. While material heterogeneity usual

Clay, feldspar and silica sand are important industrial minerals which often need treatment commonly known as beneficiation to improve the quality of ceramic tiles produced from these materials. The different minerals, after sorting, were treated separately in distilled water, alcohol and hydrochloric acid before being crushed in a ball mill; they were then characterized using a pelletron accelerator. The results show an increased silicon content for clay, silica sand and feldspar; and reduced aluminum content for clay and silica sand but not for feldspar. Iron impurity and its oxide are also

Phosphorous is indispensable in the phosphoric acid industry, fertilizers, and elemental phosphorus production due to its high economic importance. The way to successfully upgrade phosphate ore was based on a full understanding of its mineralogy, mineral surface properties, mineral distribution and liberation. Most phosphate ores are not suitable for direct use in the acidulation process because they have relatively low P2O5 contents and generally contain many impurities. Thus, low-grade phosphate ores must be pretreated to reach a suitable phosphate concentrate by the following beneficiation
