  • Froth flotation - Wikipedia
    Froth flotation - Wikipedia

    Froth flotation is a process for selectively separating of 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

Froth flotation, as pointed out previously, was a part of the evolution of milling during the first quarter of the 20th century—a period during which the progress of milling was greater than in all of its previous history. It marks the passing of the

    Such ores containing multiple metals such as lead, copper and zinc can be selectively extracted by using froth floatation. The minerals that do not float into the froth are called the flotation tailings or flotation tails. The froth flotation process was first patented by H. F. K. Pickard, E. L.Sulman and John Ballot in the year 1906

    Feb 01, 2022 Froth flotation is usually applied to concentrate copper ores and separate copper minerals from the gangue. Currently, there are a number of challenges faced by copper flotation plants and the most concerning one is the decreasing Cu head grade in contrast to the growing demand for Cu metal ( Ndoro and Witika, 2017 , Peng and Bhambhani, 2021 )

    Aug 21, 2020 The first step in this process is to crush platinum containing ore and immerse it in the reagent containing water; a process known as 'froth flotation'. During flotation, air is pumped through the ore-water slurry. Platinum particles chemically attach on to the oxygen and rise to the surface in a froth that is skimmed off for further refining
