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%. The results imply that it is possible to produce flotation collectors from various types of waste, which may be applicabe in black coal flotation. Producing and application of a suitable collector, which would be ecologically as well as economically interesting, makes an inseparable part of the flotation process.
