Water quality affects the flotation recovery of minerals and their separation. Mining-process waters become saturated with soluble salts after contact (oxidation dissolution) during crushing, classification flotation. Inorganic species, such as metal ions but also carbonate sulphate ions, may have a positive or negative effect on mineral As are always found in high concentrations process waters...

The work aimed to develop a rational technology for processing ore from the Yoshlik deposit, taking into account solution of issues integrated use mineral raw materials and environmental protection, development technological scheme. To enrich combined gravity-flotation scheme was recommended, followed by sorption cyanidation pyrite concentrate. According results research on sample it revealed t...

Thionocarbamates are the group of collectors that mostly used for flotation sulphide copper minerals, alone or in combination with xanthates depending on a mineralogical composition ore. In this paper, results study application thionocarbamates slag presented. Chemical analysis smelter sample obtained from Flotation plant Bor, Serbia, showed it contains 3.56% copper, which over 73% is form, as ...

This paper analyzes the application of global sensitivity analysis (GSA) to the improvement of processes using various case studies. First, a brief description of the methods applied is given, and several case studies are examined to show how GSA can be applied to the study to improve the processes. The case studies include the identification of processes; comparisons of the Sobol, E-FAST and M...

Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, particles are concentrated froth, and associated gangue minerals separated as tailings. However, significant amount of lost into tailings during the processing; therefore, can be considered secondary resources or future deposits copper. Particle–bubble collision efficiency particle–bubble aggreg...

Copper slag is a hard material produced from smelting copper-bearing ores. Over the years, research has prioritized utilizing as secondary source of base metals. This paper focuses on grinding/milling copper collected BCL Mine in Botswana to obtain maximum amount desired size class with minimal energy consumption. will then be followed by an integrated flotation and leaching approach recover co...

Mining and metallurgy have negative consequences for the environment [1-3] and lead to changes in geological [4] and climatic conditions [5]. Mining-metallurgy operations include the extraction, preparing of ores (crushing ore and flotation), processing of concentrates, and the disposal of waste rock and by-products. The main waste in mining and metallurgy are waste rocks, flotation tailings an...

An atomic force microscope (AFM) has been used to conduct force measurements to better understand the role of hydrophobic forces in flotation. The force measurements were conducted between a flat mineral substrate and a hydrophobic glass sphere in aqueous solutions. It is assumed that the hydrophobic glass sphere may simulate the behavior of air bubbles during flotation. The results may provide...
