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...

Designers commonly interact with products in the early phases of design in order to understand the solution space and benchmark on existing designs. Although designer-product interaction methods such as visual inspection and product dissection are recognized as a pivotal component of the engineering design process, little data is available on how these practices affect idea generation or when t...

Tabas mines in Iran have coal sources which are suitable for use in metallurgy industries as coking coal. But the high sulfur content of this coal imposes severe limitations on its utilization as the sulfur oxide gases evolved from the combustion of high sulfur coals result in acid rains and corrosion of equipments. In this work, attempts have been made to reduce sulfur from high sulfur coa...

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...

Fundamental studies of surface forces in foam films are carried out to explain the stability of foams and froths in froth flotation. The thin film pressure balance (TFPB) technique was used to study the surface forces between air bubbles in water from equilibrium film thickness and dynamic film thinning measurements. The results were compared with the disjoining pressure predicted from the Derj...

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...
