The Mobile Jaw Crushing Plant is not limited to the location of crushing operation, and it reduces the cost of material transportation.View More
While most other crushers reduce rocks by pushing them by force against metal, VSI crushers also use the rock fed into the machine to crush itself.View More
The roles of kaolinite and bentonite in copper flotation were further determined in a later study by Wang et al. (2015b) who confirmed that bentonite was more problematic than kaolinite in terms
2020-06-11· Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals.
The interaction of two clay minerals, kaolinite and bentonite with gypsum and its effects on the flotation of a copper–gold ore was investigated in this study. It was found that bentonite increased the viscosity more than kaolinite when mixed with the copper–gold ore at low shear rates.Cited by: 24
•Bentonite and kaolin caused different issues in copper flotation.•Bentonite reduced the amount of froth and decreased copper recovery.•Kaolin enhanced froth stability and decreased copper grade.•Bentonite caused high pulp viscosity reducing bubble and particle mobility.•Kaolin had little effect on pulp viscosity and moved to the froth.Cited by: 24
The effects of various amounts of bentonite and kaolin on copper flotation are shown in Fig. 2(a) and (b), respectively. Flotation tests were performed with Telfer clean ore as a laboratory baseline in the absence of clay samples. The presence of either bentonite or kaolin affected copper flotation.Cited by: 24
In this study, the flotation of a copper–gold ore in the presence of 10% bentonite in tap water and sea water was investigated. It was found that bentonite had a deleterious effect on copper and gold flotation in tap water, but this deleterious effect was mitigated in sea water.Cited by: 20
The previous study demonstrated that bentonite had a deleterious effect on copper flotation by increasing pulp viscosity, but this deleterious effect could be mitigated by sea water (Zhang et al., 2015a). In this study, the effect of different cations, Na +, K +, Mg 2+ and Ca 2+ with the same anion, Cl −, on the rheology of a copper-gold ore in the presence of bentonite and copper flotationCited by: 8
In this study, the effect of bentonite and kaolinite minerals with low and high crystallinity on pulp rheology and the flotation of copper and gold minerals was investigated. It was found that
Clay minerals such as kaolinite, bentonite and smectite, which are often associated with copper, gold and other valuable minerals, place a widespread problem in mineral flotation. There have been numerous observations of these clay minerals having a deleterious effect on mineral flotation grade and recovery, with simultaneous observations of high flotation pulp viscosity.Cited by: 39
The previous study demonstrated that bentonite had a deleterious effect on copper flotation by increasing pulp viscosity, but this deleterious effect could be mitigated by sea water (Zhang et al
2020-03-13· Clay minerals impose deleterious impacts on mineral processing. In this study, bentonite consisting primarily of montmorillonite and kaolin consisting primarily of kaolinite, were used to characterise the effect of clay minerals on copper flotation. It was found that bentonite and kaolin caused different issues in the process of flotation.

Abstract. The previous study demonstrated that bentonite had a deleterious effect on copper flotation by increasing pulp viscosity, but this deleterious effect could be mitigated by sea water (Zhang et al., 2015a). In this study, the effect of different cations, Na, K, Mg and Ca with the same anion, Cl, on the rheology of a copper-gold ore in the presence of bentonite and copper flotation was
2004-10-13· In this study, the performance evaluation of Georgia Madneuli Copper Ore flotation plant was performed using the plant data and laboratory test results. For this purpose, pulp samples were taken from the flotation circuit. All samples were dried, weighed and sieved. Size distribution of each sample was determined down to 6 µm.
