Environmental concerns regarding the use of certain chemicals in the froth flotation of minerals have led investigators to explore biological entities as potential substitutes for the reagents in vogue. Despite the fact that several microorganisms have been used for the separation of a variety of mineral systems, a detailed characterization of the biochemical molecules involved therein has not ...

The hydrophobic flocculation of galena fines induced by potassium amyl xanthate (PAX) in aqueous suspensions has been studied using laser diffraction, electrophoretic light scattering, contact angle, and microflotation measurements. The measurements were performed on <2 µm, 2-5 µm, 5-10 µm, and <30 µm size galena by varying several parameters, including PAX concentration, pH, original particle ...

The primary coexisting mineral with galena is sphalerite. Hence, it critical to selectively separate from sphalerite by flotation. In this work, thiourea and related derivatives as potential flotation collectors for separating were investigated. Thiourea its found be effective selective in batch studies of a single mineral, 1,1-diphenylthiourea (11DTA) emerging the best choice. Galena has super...

Flotation is a common process in sulfide ore beneficiation. Due to the restrictions and lack of access to high-quality water sources for industrial purposes, recycled water plays an important role in the flotation processes. Due to the existence of various organic and inorganic substances in the process, water influences the flotation performance. In this work, the effect of accumulation of sul...

This communication presents a model structure for the flotation recovery of middling particles (10–90% liberation). Fourteen datasets from literature were studied (galena flotation), which involved different systems and operating conditions. The responses allowed flexibility to be evaluated under range profiles. modelling results showed that galena can characterized by interaction between linea...

The study of the depression effect non-toxic depressants on flotation separation chalcopyrite from galena is great importance for both industrial applications and theoretical research. mixed depressant (DFinal) four common inhibitors—sodium carboxymethyl cellulose, sodium silicate, sulfite, zinc sulfate—exhibited high selectivity during galena. Flotation tests an copper–lead bulk concentrate sh...

The solid-state properties of semiconducting natural minerals have often been considered to influence their interactions with electrolytes, although the importance of these properties in this context has never been unequivocally established. For instance, differences in semiconducting properties have been proposed by Paul et al. [1] to be responsible for observed variations in the electrochemic...

In this research, the selective flotation of galena and sphalerite minerals was evaluated from a pyrite-rich lead-zinc sample. An optimum mixture of selective collectors against pyrite and also organic/inorganic pyrite depressants was obtained in the flotation of galena and sphalerite by an experimental mixture design. The effect of different collectors and pH values were investigated in the ob...
