The critical effect of phyllosilicate minerals in mineral processing and in particular in flotation performance is a well-known fact (Ndlovu, Farrokhpay, & Bradshaw, 2013). Phyllosilicate minerals ...
A variety of mineral ores have been investigated and the effects of microwave radiation quantified in terms of the mineralogy, changes in the Bond Work Index, flotability and magnetic separation.
The mining and mineral processing industries use water in all of their operations, from exploration, through mining and processing to closure. Limited availability of freshwater resources, government regulations, civil actions as well as the corporate sustainability policies and goals, put serious pressure on the mining industry.
entional effects on Air pollution, Water pollution, and impacts on land environment. After reviewing the previous study, it was found that the major environmental impacts of mineral mining and its …
For example, mining, processing and transportation require fuel and electricity, and the decomposition of carbonate minerals, employed to reduce environmental impacts, also releases carbon dioxide.
In mineral processing, ores must go through a number of different operations to obtain the final products. Thus, mineral processing involves four major steps or stages: (1) comminution or size reduction, (2) size separation, (3) concentration or beneficiation by taking advantage of physical properties, and (4) dewatering.

Kozłowski et al. analyze the long-term effects of agricultural reclamation on Technosols in a post-mining area in Central Poland. Over 43 years, the study observes improvements in the physical and water retention properties of fertilized Technosols, particularly in the surface horizons. ...

Pyrite, the most abundant sulfide mineral in base-metal deposits, presents significant challenges in mineral processing due to its deleterious effects when not properly managed. Its undesirable association with valuable minerals leads to low-quality concentrates, hindering smelting processes.
While effects of various nutrients and certain non-nutrient components of food on mineral utilization have been intensively studied, less is known about the effects of food processing and preparation procedures. Fermentation during the production of beer, wine, yogurt, and African tribal foods affec …
This review includes information on different sources of mining waters and its effect on groundwater contamination and ecological effects.
This paper analysed and summarised the significant research outputs published on the environmental impact assessment of mining and mineral processing industries through life cycle assessment.The paper presents valuable insights in identifying the gaps, where should the focus be in the mining and mineral processing industries for a sustainable future. . Mining and …
The processing of food is a common method that converts raw materials into edible items that are safer, simpler to prepare and frequently more appealing to customers this change however has ...
At the particle sizes typically associated with fine grinding in minerals processing (<75 μm), viable options for quantitative particle shape characterisation are limited, and effects of image resolution are of particular concern (Little et al., 2015, Varinot et al., 1997). Scanning electron microscopes provide higher resolution than optical ...
The paper presents valuable insights in identifying the gaps, where should the focus be in the mining and mineral processing industries for a sustainable future. Mining and mineral processing industries have been the key focus of research in many countries due to its increasing sustainability concerns that affect global warming and climate change.

The cavitation effect and acoustic radiation force effect are two significant effects of ultrasound that occur in water. These two effects depend on various influence factors according to the ultrasonic mechanism (see Section 2). It should be noted that cavitation effects can be significantly changed at different frequencies and pressures.
This review highlights the food sources, biological functions, absorption mechanisms, bioavailability assessment methods and some enrichment solutions of minerals. The effect of various processing and storage technologies on the mineral content of some important food products has also been precisely reviewed.
Mining and mineral-processing wastes are one of the world's largest chronic waste concerns. Their reuse should be included in future sustainable development plans, but the potential impacts on...
The rheology effect in grinding operations was the first to draw the attention of researchers to the correlation between rheology and mineral processing operations. It was found in 1985 that the grinding medium tended to be centrifugal when the slurry viscosity exceeded a specific value (named the critical value), which resulted in the balls ...
Mineral processing, also known as ore dressing, mineral beneficiation, or mineral engineering, is defined as the science and art of separating valuable metallic and nonmetallic minerals from unusable gangues.
Without proper precautions, these efforts could come with serious side effects in communities located near critical mineral mines and processing facilities. So it's crucial that governments and companies along the value chain take steps to better measure and manage the water-related risks associated with critical minerals.
High-pressure preservation/. Total carotenoids in fruits and vegetables are relatively resistant to HPP and thermal processing. The majority of researchers discovered that high-pressure preservation had no effect on the total carotenoid content of fruits and vegetables, or even boosted it [25,26].

The effects of mineral processing wastewater on sulfide minerals were investigated by flotation, infrared spectrometry and electrochemistry test. The results show that lead-concentrate water can ...
Mineral processing involves the liberation and concentration of economical metals and minerals from mineral resources for metal extraction (Lottermoser, 2010). The economic purpose of mineral processing is two-fold: firstly, it reduces the bulk of the ore that needs to be transported and processed for metal extraction by using relatively cheap ...
