Processing of materials that originated from tailings industrial plants (with a wide range particle size distribution, “PSD”) without grinding has several advantages since mines are faced with lot pressure to minimize their environmental impacts. This article indicates the introduction submicron bubbles (known as nanobubbles, “NBs”) conventional flotation could improve separation efficiency val...

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...

Can the DLVO theory predict foamability of flotation frothers as MIBC (methyl isobutyl carbinol)? The froth is a multi-bubble system, in which bubbles collide, thus either coalescing or rebounding. This scenario driven by hydrodynamic push force, pressing towards each other, electrostatic and van der Waals forces between bubbles, occurrence precipitation dissolved air bubbles. We studied 20 ppm...

This short communication evaluates a new strategy to sample bubbles in gas dispersion characterizations. Bubble size is measured bidimensional flotation cell using the McGill bubble analyzer under different types of frothers, frother concentrations and superficial rates. The original design this viewer modified, changing deflecting system photograph only fraction entering device. As result, inc...

In order to increase the recovery of PGMs by flotation, it is necessary optimise liberation key minerals in which platinum group elements (PGEs) are contained include sulphides, arsenides, tellurides, and ferroalloys among others, while at same time ensuring optimal depression gangue minerals. achieve this, comminution circuits usually consist two or three stages milling, first stage autogeneou...
