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 valuable minerals, such as copper- and le

Originating in the mining industry for enrichment of ores, the flotation process developed in Europe for deinking has gained importance in North America. In this process, hydrophobic particles such as ink and small contaminants attach to air bubbles injected into the pulp and get carried upward to the froth while fibers remain in the bulk.

Flotation Froth - an overview ScienceDirect Topics

However, this process is based upon density alone and should not be confused with the process of froth flotation. Thus, the process of froth flotation is not solely dependent upon the density of the material; it is also dependent upon its hydrophobic nature. For example, froth flotation is a technique commonly used in the mining industry.

The future of flotation - CIM

Nov 04, 2016 It is intended specifically for an innovative flowsheet that addresses one of the biggest problems mining operations face: With more tonnages to process, and more fine-grained ore, comminution is demanding ever more energy. If flotation circuits could handle coarser particles, then energy could be saved in the comminution circuit.

1 Froth Flotation – Fundamental Principles

Table 1: Grade/recovery performance of a hypothetical copper ore flotation process. Product % Weight % Cu Assay Feed 100 2.09 Concentrate 10 20.0 Tailings 90 0.1 (a) From Table 1, the Ratio of Concentration can be calculated as F/C = 100/10 = 10. If only assays are available, the ratio of concentration equals (20 – 0.1)/(2.09 – 0.1) = 10 ...

Mining Industry Copper Sulfide Ore and Flotation Process ...

Jul 09, 2019 1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.

Separating Minerals by Floatation

The floatation process can separate a desired mineral such as copper, nickel, molybdenum, or zinc from ore. Floatation can separate the desired mineral from waste materials or from another mineral. Industry: Mining

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 article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

flotation process Infoplease

flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore. Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.
