Využití pyrolýzních olejů ve flotaci uhlí

Abstract

In this paper we are focusing on testing and comparing of new flotation reagents, that are being produced by pyrolysis of waste materials formed during flotation of charcoal stay. Flotation experiments took place on a sample of charcoal stay from mine Darkov OKD, a.s.. In the experimental part, the produced pyrolysis oils are analysed and methods of conducting flotation tests, whose results are stated in the tables and evaltued in conclusions section, are being discussed. From obtained results, it is clear, that in the comparison of used pyrolysis oils the oil made from sunflower husks was the most convenient.
