The wettability of a solid is often represented by its critical value of surface tension of wetting (γ c) to achieve selectivity in froth flotation, adhesion in oil agglomeration, …
The attachment between a bubble and a particle (see Fig. 1) is commonly described as requiring a minimum, 'critical' time to occur, once the two bodies are brought into proximity; this is the induction period, τ (Sven-Nilsson, 1934).In flotation, the conventional theory compares τ against the time available for a particle to slide over the bubble's surface (Nguyen and …

How the data is used to determine flotation kinetics is a subject of a separate video. The key aspects are: the types and setup of the laboratory cell; sample to be tested, test conditions and; how the test is conducted. The standard laboratory cell and cell size for many decades has been the Denver D12 with 2.5 litre stainless steel cell.
The physical activities in a flotation cell involve the movement of solid particles driven by the flow of air and liquid. As illustrated in Fig. 1, Fig. 5, considering the different roles of pulp and froth in determining the cell dynamics, the flotation cell is divided into two sections: froth volume and pulp volume.The froth volume and pulp …
More ores are treated using froth flotation cells than by any other single machines or process. Non-metallics as well as metallics now being commercially recovered include gold, silver, copper, lead, zinc, iron, manganese, nickel, cobalt, molybdenum, graphite, phosphate, fluorspar, barite, feldspar and coal. Recent flotation research indicates that any …
Research related to various microscale bubble–particle collision processes occurring in flotation has been considered only under some ideal assumptions, for example, quiescent fluid environments (Sherrell, 2004). ... In CFD modelling, a flotation cell is discretized into individual finite volumes (or cells) where local values of flow fields ...

The macroscale flow fields in a flotation cell are influenced by flotation cell geometry and structure, inlet and exit configurations, impeller structure and tip speed, air nozzle structure and air flow rate, the properties of liquids and particles and so on. In a typical industrial scale flotation cell, there are millions of bubbles and particles.
