froth flotation method

  • How can the froth floatation process be described? - Quora

    Aug 14, 2019 · For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral surfaces are naturally hydrophobic, requiring little or no addition of collector).

  • Froth Floatation Process

    Froth Floatation Process In some cases for example, sulphides ores of copper, zinc and lead concentration is brought by this method. In this method advantage is taken of the referential wetting of the ore by an oil.The finely ground ore is taken in a tank containing water and 1% of pine oil or terpentine oil .

  • 1 Froth Flotation – Fundamental Principles

    Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry.

  • Froth flotation | ore dressing | Britannica

    Froth flotation, separation of minerals differing little in density but greatly in wettability by surfactants that stabilize a froth formed on the surface of an agitated suspension of the minerals in water. See flotation. This article was most recently revised and updated by Erik Gregersen, Senior Editor.

  • What is Froth Flotation?

    Sep 29, 2019 · Froth flotation is a process using air bubbles to separate materials based on their relative affinity to water. Bubbles carry reagent and hydrophobic materials to the top of a tank where they can be removed. Froth flotation has been used for more than a century in mining operations to separate valuable materials from excavated ores.

  • Froth Flotation Technique Method Procedure

    Frothers are the reagents necessary to produce the mineral- carrying froth. The quantity consumed is 1/20 to 1/5 pound per ton of ore. For sulphide flotation various wood oils have been used, the most common being pine oil, particularly steam-distilled. Cresylic acid is a common frother of another type.

  • Introduction to Mineral Processing - Chevron Phillips Chemical

    Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.

  • Flotation | ore dressing - Encyclopedia Britannica

    Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to
