23.2: Principles of Extractive Metallurgy Chemistry

Aug 25, 2020· Concentration of ores may be achieved by froth flotation in which an ore is contained in a froth that floats at the top of a water vat. After the ore has been concentrated it must be roasted to a high temperature allowing for the desired metal to be oxidized.

Apr 10, 2019· The physical methods include traditional handpicking, hydraulic washing, magnetic separation, and froth floatation for the ore concentration. Hand-picking. It was the traditional method of concentrating ore directly with hands. In this method, the gangue or adhering solid matrix is separated from the ore with a hammer’s help.

Sulfide Ores an overview ScienceDirect Topics

The universal technique for this concentration is froth flotation of finely ground ore. Froth flotation entails attaching fine Cu-sulfide mineral particles to bubbles and floating them out of a water–ore mixture. The flotation is made selective by using reagents, which make the Cu-sulfide minerals water-repellant (hydrophobic) while leaving

Mineral processing Concentration Britannica

Flotation is the most widely used method for the concentration of fine-grained minerals. It takes advantage of the different physicochemical surface properties of minerals—in particular, their wettability, which can be a natural property or one artificially changed by chemical reagents.

Mineral processing Wikipedia

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.

Separation and Concentration Mineral Processing

6. Separation and concentration. Following milling, the ore is subjected to different processes according to its nature. Pulp may require to be thickened ahead of these processes in large tanks called Thickeners, in which the solid component is allowed to settle and is raked towards the centre by large, rotating rakes while relatively clear water overflows into a peripheral drain or Launder.
