Pyrolitics Oils in Coal Flotation

, 2014
The aim of this article was the research of new flotation reagents, which were formed through pyrolysis of different types of waste. Potential new flotation reagents are liquid organic phase pyrolysis of tires, plastic and wooden materials. Another goal is to achieve the coal flotation ash content quality below 10%.

Reverse flotation as a method of coal cleaning for preparation of coal-water slurries

, 2002
Due to strongly attractive hydrophobic forces that operate between hydrophobic particles in water, aqueous suspensions of bituminous coals are characterized by high yield stresses and behave as non-Newtonian systems.
