A bank of 4 Denver Sub A Flotation Cells, 750 Cubic Foot per cell, overflowing the froth product. Flotation is used in gold, mineral processing, copper, coal, to recover fine particles, typically finer than 0.5 mm. Chemical and physical attachment of the solid particle to the bubble, induced by the chemical reagents and conditioners would be a over simplified description of froth flotation.

Multidimensional Optimization of the Copper Flotation in a

Three factors were measured in the flotation process of copper ore: the copper grade in a concentrate (β), the copper grade in tailings (ϑ), and the recovery of copper in a concentrate (ε). The experiment was conducted by means of a Jameson cell. The factors influencing the quality of the process were the particle size (d), the flotation time (t), the type of collector (k), and the dosage

[PDF] CFD MODEL OF A SELF

The effect of impeller speed on the air flow in a selfaerated Denver laboratory flotation cell was investigated using computational modelling. Air is induced into the slurry by the impeller's rotating action. The rate of air flow is determined by the suction pressure created by the impeller, the hydrostatic head of the slurry and the frictional losses along the delivery shaft from the inlet

Processes

Flotation constitutes a gravity separation process, which originated from the minerals processing field. However, it has, nowadays, found several other applications, as for example in the wastewater treatment field. Concerning the necessary bubble generation method, typically dispersed-air or dissolved-air flotation was mainly used. Various types of biological materials were tested and floated
