Jul 23, 2014 Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water).

Descriptions of the use of a flotation process have been found in ancient Greek and Persian literature suggesting its antiquity. During the late 19th century, the process basics were discovered through a slow evolutionary phase. During the first decade of the 20th century, a more rapid investigation of oils, froths, and agitation led to proven work-place applications, especially at Broken Hill, Australia, that brought the technological innovation known as “froth flotation.” During the early 20th century, it dramatically revoluti

Gold Flotation - Mineral Processing Metallurgy

Where a high sulphide recovery is demanded, flotation methods are now in general use, but in the days before flotation was known, a large part of the world’s gold was recovered by concentrating the gold-bearing sulphides on tables and smelting or regrinding and amalgamating the product. Though the modern trend is away from the use of tables ...

Silver Gold Recovery Flotation Process

The ores from which silver and gold are recoverable by flotation divide themselves naturally into two general processing classes: ores in which the valuable minerals are those of the base metals, the precious metals being incidental constituents, and ores in which the gold and silver are of primary importance, the base-metal minerals, if present, being of little or no value. The first class ...
