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 this research, cerium recycling was studied by Adsorbing Colloid Flotation (ACF). Ten important parameters including collector type and dosage, cerium and colloid concentrations, frother type, activator type, preparation and frothing time, air flowrate and pH, each in two levels, were investigated. Statistical design of experiment was implemented for process modelling and analysis of var...

(2008), doi:10.1016/j.minen Froth flotation for beneficiation of printed circuit board comminution fines was investigated in this work, via reverse flotation under a scheme described as natural hydrophobic response. With no reagents, the scheme employed variation of kinetic parameters of airflow rate and impeller speed to optimize m...

Investigations were carried out on the effective utilization of blast furnace flue dust samples obtained from the two integrated steel plants at Rourkela and Jamshedpur. The samples essentially contained unburnt coke and iron rich grains as the value added products. Flotation technique was employed to recover the carbon values present in the sample. It was possible to obtain a product containin...

In this study, grinding + flotation experiments were performed on the sample of complex Pb-Zn sulphide ore taken from Niğde (Ulukışla-Madenköy) region in Turkey. According to mineralogical analysis used experimental studies, it was determined that composition contains calcite, quartz, pyrite, chalcopyrite, hematite, goethite, limonite, gypsum, galena, sphalerite, jarosite, arsenopyrite and marc...

The relation between rate constant k1 and absolute temperature T for graphite, anthracite, coal floated with only frother was investigated using combined theoretical empirical approaches. It determined that the lnk1 1/T is curvilinear requires a polynomial of second degree sufficient approximation experimental data points. Therefore, well-known Arrhenius formula chemical reactions, predicting l...

A considerable difference exists between the flotation separation of artificial minerals and real low-grade ores processing where selectivity would be main issue. Nanobubble-assisted (NB) investigations have been mostly examined with pure materials a narrow particle size range, less on complex sulfide ores. This study considered NB for Pb-Cu-Zn ore in two different ranges various conditions to ...

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...
