With Flotation Watch the stiffness of the flotation froth can be measured and this helps to keep the recovery in higher level. The signals for the production failures, such as hardening and collapse of the froth bed, can be seen beforehand and avoided. This way we can help to minimise the losses in the flotation process, says Hakola.

A Brief Review of Pulp and Froth Rheology in Mineral Flotation

Descriptions of the use of a flotation process have been found in ancient Greek and Persian literature suggesting its antiquity. During the late 19th century, the process basics were discovered through a slow evolutionary phase. During the first decade of the 20th century, a more rapid investigation of oils, froths, and agitation led to proven work place applications, especially at Broken Hill, Australia, that brought the technological innovation known as froth flotation. During the early 20th century, it dramatically revoluti

Froth floatation process is used to concentrateic ores.

Froth floatation process is used to concentrate sulphide ores. In some cases, sulphide ores of copper, zinc and lead concentration are brought by this method. It is the referential wetting of the ore by an oil. A strong current of air is blown through the suspension producing a heavy froth e.g. Galena P b S is associated with Sphalerite Z n S and Pyrite F e S.
