Froth floatation process for the concentration of ores is a practical application of :

Explanation

Froth flotation is a widely used process for separating valuable minerals from gangue (unwanted material) in ore minerals. It relies on the differences in the surface properties of minerals to selectively separate them. Here's how adsorption applies to the process:Collectors and Frothers: In froth flotation, chemicals called collectors are used to selectively bind to the surface of the target minerals, making them hydrophobic (water-repellent). Frothers are added to create a stable froth on the surface of the flotation cell.Formation of Froth: The mineral-laden mixture is aerated, and air bubbles attach to the hydrophobic mineral particles, carrying them to the surface of the flotation cell to form a froth layer.Selective Separation: The froth, containing the hydrophobic minerals, is skimmed off, while the hydrophilic (water-attracting) gangue minerals sink and are discarded. This results in the selective separation of valuable minerals from the ore.Adsorption: The success of froth flotation relies on the adsorption of collectors on the surface of the mineral particles. Collectors adsorb preferentially onto the mineral surfaces, changing their surface properties and allowing them to attach to air bubbles in the flotation cell.
