Flotation | ore dressing | Britannica

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

OverviewHistoryIndustriesPrinciple of operationScience of flotationFlotation equipmentMechanics of flotationChemicals of 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

Reagents in iron ores flotation - ScienceDirect

Queiroz (2003) verified that, for certain itabirite ore types, the use of attrition allows the increase of the mass recovery to the slimes and flotation concentrate fractions and the decrease of iron grade in the flotation tailings, iron grade in the slimes and SiO 2, Al 2 O 3 and P grades in the concentrate, resulting in higher figures for Gaudin’s selectivity index.
