ore dressing flotation process important

flotation ore dressing Britannica

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This

Mineral Flotation SpringerLink

Abstract. In the extraction of metals from their ores, the process of mineral flotation plays a most important role. Flotation provides the means of separating and concentrating the valuable components of an ore to produce a grade of mineral concentrate suitable for feeding to efficient pyrometallurgical or hydro-metallurgical operations.

CHAPTER 1 MINERAL DRESSING - Webs

The crude ore from the mines contain a number of solid phases in the form of an aggregate. The valuable portion of the ore is known as mineral while the worthless portion is known as gangue. During ore dressing, the crude ore is reduced in size to a point where each mineral grain becomes essentially free so as to make separation between them.

Flotation of iron ore Iron ore minerals, particularly hematite and goethite, are beneficiated by combination of size fraction, pre-concentration and flotation in stages ( Fig. 12.47 ). Iron ores require removal of silicate impurities of a finer size by flotation for higher grade products of +60% Fe.

2021-11-24  Froth flotation machine is generally used for the concentration of sulphide ores. The principle behind froth flotation process is that sulphide ores are preferentially wetted by pine oil whereas gangue articles are wetted by water. In this process, the suspension of a powdered ore is made with water. Collectors like pine oil, fatty acids and ...
