Flotation Froth - an overview | ScienceDirect Topics Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.

Froth flotation - Wikipedia 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 valu

Froth Flotation - Metallurgist & Mineral Processing Engineer Lime is often used in flotation to increase the alkalinity of the pulp. An alkaline pH increases the volume of the froth (possibly increasing the rate at which mineral is recovered), and depresses pyrite. Frothers such as pine oil and Dowfroth 250 are used to create a froth capable of carrying or holding the mineral-laden bubbles.

Lime use and functionality in sulphide mineral flotation: A ... Rougher flotation – Lime is added after primary (typically SAG) and secondary (ball) milling, usually in a conditioning tank, to ensure optimal pH control in the subsequent rougher flotation process. 3. Regrind – Lime is added to the concentrate regrinding feed to counter a pH drop during regrinding, due to fresh exposure of sulphide surfaces. 4. Author: M. Zanin, H. Lambert, C.A. du PlessisCited by: 4Publish Year: 2019Froth Flotation Process - Mineral Processing & Metallurgy Froth Flotation Process.
