Flotation, in mineral processing,method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—thatis, thesurfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to
Milling equipment, mineral processing equipment and building materials equipment. And they are mainly used to crush coarse minerals like gold and copper ore, metals like steel and iron, glass, coal, gravel, etc.
Spiral chute separator is the best equipment for mining and ore beneficiation. It is a kind of ideal equipment for mining sand.
The circular vibrating screen is a vibrating screen with high efficiency and it advantages include stable structure, strong exciting force, high efficiency, low vibrating noise, durability, handy maintenance and safe operation.
Chute feeder is a kind of feeding equipment which is earlier used in storage trough and it is suitable for the short-distance transport of metallic and non-metallic materials.
This series screen is always used in processing minerals such as ferrous metals including hematite magnet and nonferrous metals including lead, zinc, gold and silver, etc.
The combination crusher is a new generation high efficiency crushing machine designed and researched by integrating the domestic and foreign crusher technology with the same kinds and optimizing the main technical parameters.
Apr 06, 2020· Flotation is theprocess of separation of beneficial minerals from a mixture by creating froth on which minerals separateout. This method of froth floatation is a method of mineral processing in which different minerals are separated selectively. Such ores containing multiple metals such as lead, copper and zinc can be selectively extracted by using froth floatation.

Flotation is aneconomical and effective separation of refined gold technology,especially for these ores that are not suitable for other processes, such asgold-bearing copper ore,base metal ore,copper-nickel ore,platinum group ore,etc. Flotation is also used to remove impurities before hydrometallurgical treatment (ie, carbon pre-flotation) to purify low-sulfide and refractory ores for further processing.

Flotationprocesses are based on the different surface wettability properties of materials (Wang et al., 2015). In principle,flotationworks very similarly to a sink and floatprocess, where the density characteristics of the materials, with respect to that of the medium where they are placed are at the base of theseparation.
