An Overview of Optimizing Strategies for Flotation Banks

This is illustrated in Figure 9 for a 2 cell bank where the total cell volume is fixed but the volume of each cell is altered, which is equivalent to changing cell recovery. Setting total bank recovery when cells are equal volume (V 1 /V 2 = 1) at 75%, we note that all other volume combinations give less than 75%.

However, model selection criteria were not adequately discussed from the statistical points of view. In this investigation, the kinetic behavior of a complex copper sulfide ore was studied in a mechanical Denver flotation cell focusing on flotation kinetics of chalcopyrite, pyrite and molybdenite.

Froth flotation

Froth flotation

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Microcel flotation columns in addition to producing high concentrate grade, increase product recovery and improve plant profitability. The patented Microcel sparger technology enhances metallurgical performance by allowing an unprecedented flexibility on the grade recovery curve.

Optimisation of gold recovery by selective gold flotation

Optimisation of gold recovery by selective gold flotation

Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free. Gold does float readily, however, and the free gold can be selectively floated

Introduction to Mineral Processing Chevron Phillips Chemical

Introduction to Mineral Processing. The process of froth flotation entails crushing and grinding the ore to a fine size. This fine grinding separates the individual mineral particles from the waste rock and other mineral particles. The grinding is normally done in water with the resultant slurry called the pulp.
