The Cerattepe (Artvin) mine contains volcanogenic massive sulfide (VMS) deposits in northeastern Turkey. This is a kuroko type deposit located Late Cretaceous volcanic, intrusive and sedimentary rocks, has structure with dense alteration stages. In this study, batch flotation tests were carried out to determine the behavior of new sample (mix ore), that was combination two different ores behavi...

Dynamic frothability index (DFI) is a characteristic of any frother which presents useful information about frothing properties. The objective of this study is to introduce a prediction model for estimation of DFI value of dual-frother blends. Model uses the DFIs of frothers and mole ratio of weaker frother to calculate the blend’s DFI. The model reliability was confirmed by comparing the exper...

The present study investigates the optimization and advanced simulation of flotation process coarse particles (–425 + 106) using micro-nanobubbles (MNBs). For this purpose, experiments in presence absence MNBs were performed on quartz particles, results statistically analyzed. Methyl isobutyl carbinol (MIBC) was employed as a frother for generating through hydrodynamic cavitation. significance ...

This paper is one of a study that implements reverse flotation methods as an alternative beneficiation on bauxite processing. aimed at decrease silica content and increase alumina in so its qualified feed Bayer Process. The experiments were carried out 1375 mL cell tank. Dodecylamine (DDA) AERO 3000C used the collector, starch depressant, Dowfroth 1012 frother. overall conducted solid to soluti...

Graphite ore collected from Hunan province, south China was characterized by chemical analysis, X-ray diffraction, and optical microscopy. Rougher and multi-stage flotation tests using a mechanical flotation cell and a flotation column containing an additional centrifugal force field were carried out to promote its grade and economic value. In rougher flotation, both the mechanical flotation ce...

The influence of conditioning on the flotation of pyrrhotite in the presence of chlorite was investigated through flotation tests, sedimentation tests, and X-ray photoelectron spectroscopy (XPS) analysis. The flotation results show that chlorite slimes dramatically impair the flotation of pyrrhotite. Sedimentation and flotation tests reveal that conditioning can effectively remove chlorite slim...

The molecular structure of the liquid–vapor interfaces aqueous solutions alkali metal halides and methyl isobutyl carbinol (MIBC, (CH3)2CHCH2COCH3) is determined by using dynamics simulations with polarizable force fields for first time. salts are chlorides, iodides, some which found in raw partially desalinated seawater increasingly used flotation operations regions affected severe prolonged d...

partially replace oil and natural gas as fuel sources. Of all the coal-cleaning pmesses, flotation is one. of the most versatile. Carbon dioxide coal flotation is a new technology developed at the University of Utah.(l) Compared with conventional flotation, carbon dioxide flotation enhances the ash rejection and increases flotation recovery for coals of different rank with the exception of lign...
