Kinetic models are the most important tools for the prediction and evaluation of the flotation circuits performance. In order to determine the kinetic order and rate of flotation of a Gilsonite sample, flotation experiments were conducted using the combination of Gasoline-Pine Oil, and one test without any collector and frother. The pulp density was 10% and the experiments were carried out in b...

a new method was introduced for frothing characterization of flotation frothers. method uses water recovery to develop a new frothability index named water recovery index (wri). new index was determined for some commercial frothers and results were compared with dynamic frothability index (dfi). results showed that water recovery index values follow the order of a-65 13016 s/mol > df-250 6292.4...

Methylene blue was efficiently removed from aqueous solution by foam flotation using a rhamnolipid a biosurfactant as a dye collector. The effects of four parameters, namely, pH (1.5–11.5), frother concentration (5–65 ppm), aeration rate (2–6 L/min) and rhamnolipid to methylene blue weight ratio (0.5–6.5), on dye removal were studied and optimized using response surface methodology. Results...

It is well-known that entrainment of particles into the froth is a key factor in the selectivity and performance of the flotation process, especially for fine particle recovery. Since flotation is a continuous process, in this work, the effects of operating parameters on the entrainment of ash materials in a sample coal flotation is investigated from a time-sequence viewpoint. The effects of th...

Flotation is one of the most used methods to upgrade natural graphite resources. However, efficiency usually decreased due entrainment undesirable fine gangue minerals. In this work, impact different factors such as particle size, pulp density, and flotation reagent on mica quartz in a flake was studied. The single mineral results showed increased when reducing size minerals increasing density....

Negatively Biased Flotation Column (NBFC) is a tool, which developed for the flotation of coarse-sized ores. Unlike conventional column, in this there no froth zone and wash-water usually not used. Therefore, hydrodynamically entrainment fine-sized particles into concentrate possible, may result decrease grade or yield concentrate.
 In study, operating parameters that can affect were inves...
