Variables of hydrodynamics are equally important as those of surface chemistry in
determining the efficiency of froth flotation processes. In a mechanical flotation cell, macro …

A knowledge of hydrodynamic characteristics is important because it helps in design,
control, analysis, optimization, operation, and modelling of the system, which enhances the …

th The technology of froth flotation, invented in the early 20 century was first used for the
concentration of sulfide minerals. Since then it has been applied for the processing of many …

In modeling flotation, the process of bubble–particle interaction is usually divided into three
subprocesses, including collision, adhesion and detachment. Of these, the hydrodynamics …

Only when the process of particle detachment is well understood and modelled can minerals
recovery using the flotation process be modulated to achieve a high efficiency by suitably …

Fundamentally based computational models are developed and applied to quantify the
removal of inclusions by bubbles during the continuous casting of steel. First, the attachment …

The flotation upgrading of low-rank-coal is more difficult to achieve than that of bituminous
and/or anthracite coal, especially for micro-fine coal slime, because of developed porosity …

A comprehensive review of the published literature regarding the computational fluid
dynamics (CFD) modelling of the flotation process is presented. The detailed principles …

Cationic reverse flotation of quartz is the most important technique for the concentration of
itabirite iron ores for the production of pellet feed. Mineral processors dealing with this …

The first-order flotation rate is directly proportional to the superficial gas rate and varies
approximately as the inverse cube of bubble size, suggesting that decreasing bubble size is …
