OverviewHistoryIndustriesPrinciple of operationScience of flotationFlotation equipmentMechanics of flotationChemicals of 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. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of froth flotation has improved the recovery of valuable minerals, such as copper- and le

Froth flotation is again employed to produce marketable concentrates of both. The process is identical in principle to the flotation of other minerals. The figure on the right is a simplified version of a Pb/Zn flotation circuit. The main difference in lead/zinc flotation is that zinc is usually depressed while lead (and copper) is floated.

Flotation Depressants - Mineral Processing Metallurgy

First let’s change the amount of the Flotation Depressants used. The valuable mineral that isn’t liberated from the unwanted mineral will begin to be depressed along with the waste. For the floatation operator, the change that will become most apparent is, that the color of the froth will begin to reflect more of the wanted mineral’s color.

In entrainment and flotation tests carried out on lead-zinc and copper ores of different fractions the froths observed were highly stable (lead-zinc) to brittle (copper ore). The bubble sizes varied from small (at higher frother concentrations,40-100 mg/l) to large (at low frother concentrations,5-20 mg/l).

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.

Lead-Zinc ores

The copper ions replace zinc atoms on the sphalerite surface creating a pseudocopper mineral surface coverage on the sphalerite which is then collected using copper flotation type collectors. Because most of the iron sulphides also report to the lead flotation tails and so feeds the zinc flotation circuit, typically lime is used to raise pH for ...
