Froth Flotation Process - 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. This is because the froth is becoming purer …

Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles.

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.

Dec 15, 2019· This approach could be implemented in froth flotation, the main process used to concentrate copper sulfide ores, by replacing the chemical reagents (i.e., collectors, frothers, and modifiers). These regents are used to control the particles' superficial wettability and induce floatability over desired mineral selectivity ( Herrera-Urbina, 2003 ).

Flotation Frothers - Frothing Agents

Flotation is often used in combination with flocculation (Besson and Guiraud, 2013; Kwon et al., 2014). The use of flotation to concentrate flocculated microalgal suspensions has some advantages over gravity sedimentation. High biomass concentrations can be achieved in the froth that is skimmed from the surface.

Dissolved Air Flotation (DAF) Systems

During the flotation process, frothers help create the ideal hydrodynamic conditions (such as bubble size and gas holdup) required within the pulp in the flotation cell. They generate froth that is stable enough to hold collected minerals on top of the pulp, mobile enough for removal, and decays quickly to assist with downstream operations.
