New directions in flotation machine design ScienceDirect

01, 2010 · A new cell has been developed, the Concorde Cell, in which the preaerated feed is raised to supersonic velocities before passing into a highshear zone in the flotation cell. The local dissipation rate is of the order of 100 kW/m 3 , one to two orders of magnitude higher than is available in conventional mechanical cells.

differences Is it "flotation"or "floatation"? English

Some results for floatation and flotation with various related terms are below. M = millions of hits. k = 1000's of hits. e.g. "Australia 420 k / 10.9 M"= 420,000 hits for floatation and Australia, 2.29 million hits for Australia and flotation. Very obviously this method has methodological deficiencies, but it is also demonstrably useful.

The Depressing Effect of Kaolinite on Molybdenite Flotation

Coppermolybdenum grades of important mining deposits have progressively decayed, which is associated with high levels of clay minerals which affect froth flotation. The depressing effect of clay minerals on copper sulfides was previously reported but there are no systematic studies on the effect on molybdenite flotation in seawater. The objective of this work was to study the effect of

A new empirical model to calculate bubble size in froth

05, · 1. Introduction. Bubble size is one of the most important parameters of gas distribution in flotation process with a significant effect on the flotation efficiency [1,2].In fact, the superficial levels of the gas bubble and gas holdup, which are related to the transfer capacity of minerals are both affected by bubble size [].

The modelling of froth zone recovery in batch and

This paper proposes an integrated methodology for modelling froth zone performance in batch and continuously operated laboratory flotation cells. The methodology is based on a semiempirical approach which relates the overall flotation rate constant to the froth depth (FD) in the flotation cellfrom this relationship, a froth zone recovery ( R
