1 Froth Flotation Fundamental Principles

Froth flotation is a good example of an engineering system, in that the various important parameters are highly inter related, as shown in Figure 1. It is therefore important to take all of Chemistry Components Collectors Frothers Activators Depressants pH Equipment Components Cell Design Agitation Air Flow Cell Bank Configuration

Optimizing Flotation Cells Flotation Cell Level Measurement

Flotation Cells (Froth Flotation) were developed to separate and recover high value Sulphide ores from low grade ore bodies. The ore is crushed and milled at the concentrator in a process known as comminution, where the mineral is in suspension in slurry.

Flotation Cell Level Measurement

The FloLevel system, because of its repeatable level accuracy measuring Pulp/Slurry height and Froth height, as well as having the capability to measure Froth Density and Froth Flow Rate, will increase the mineral recovery and reduce costs of routine sampling and laboratory testing.

Laboratory Flotation Testing Mineral Processing Metallurgy

Batch Froth flotation Testing is a means of treating a pulp of finely ground ore so that it yields the valuable or desired mineral in a concentrate that will be amenable to further processing. The process involves the imparting of a water repellent (hydrophobic) character to the wanted mineral particles by chemicals that are called collectors or promoters.
