Flotation Machine - an overview ScienceDirect Topics

Machines with large specific surface areas are generally preferred for coal flotation, due to the fast flotation kinetics of coal and the large froth solids loadings. Flotation machines with individual cell volumes of up to 28 m 3 are commonly used due to advantages in terms of capital, operating and maintenance costs. Some manufacturers also ...

Coal Flotation - an overview ScienceDirect Topics

The bubbles should be able to carry the coal to the surface without breaking, and once out of the flotation machine, it should break down (Parekh, 2000). Because of increasing price and extensive use of pine oil as a frother in Indian coal washeries ( Battacharya and Bandopadhya, 1994 ), a study was conducted in a laboratory to find a substitute.

Enhancement of Flotation Performance of Oxidized Coal

2021-11-16  Conventional hydrocarbon oil cannot adhere effectively to oxidized coal, resulting in a low yield of clean coal. In this study, a high-speed homogenizer was used to emulsify LDD (laurylamine dipropylene diamine) and kerosene, which enhanced the flotation efficiency of oxidized coal. The flotation results showed an increase from 4.12% (only kerosene) to 23.33% (emulsified oil).
