Equipment Used Flotation Of Coal. Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process
Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.
Working principle of coal flotation machine. published date: 10-08-2020. 1. The adjustment of pulp and the addition of flotation reagent. The purpose is to cause the difference in mineral surface properties, that is, to change the wettability of the mineral surface and adjust the selectivity of the mineral surface, so that some mineral particles can be attached to the air-saturation, while
Dilip Kumar, Deepak Kumar, in Sustainable Management of Coal Preparation, 2018. 5.4.6 Flotation Equipment. The basic objective of a flotation device is to keep the pulp in suspension and provide the air bubbles. The size of air bubbles matters as it controls flotation kinetics as well as the carrying capacity of the bubbles.
A frothing agent is usually added to help stabilize the froth, which is skimmed off and becomes the clean coal product. A flotation aid such as fuel oil may also be used to increase the hydrophobicity of the coal and to help collect the particles. Flotation works well for ash removal but, largely, leaves the pyrites with the clean coal.

Eriez Flotation has also made significant advances in fine coal recovery with flotation systems to recover classified and unclassified coal fines. The company’s flotation columns are used extensively in many major coal preparation plants in North American and internationally.
