Flotation Process - an overview ScienceDirect Topics

The feature making emulsion flotation different from conventional flotation is the presence of a collector in the form of oil droplets, which must collide with mineral particles in order to enhance the probability of particle- to-bubble attachment. The process is based on selective wetting: the droplets of oil can adhere only to particles that ...

Flotation - Mineral Processing Metallurgy

Jan 12, 2016  The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the concentrates in a subsequent series of metallurgical

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.

FLOTATION TECHNOLOGICAL - Martin Vialatte

In order to ensure a successful flotation, it is important to respect the following parameters: Enzyme treatment Enzymes must be added to the must in advance in order to break down the pectins that keep the particles in suspension. Indeed, the viscosity of the must is a limiting factor for the smooth running of the flotation process.

Froth flotation - Wikipedia

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
