Application of brown coal pyrolytic oils in black coal slurry flotation

Original language description

This paper deals with the possible use of brown coal pyrolytic oils prepared and applied as described below. First, brown coal samples were drawn from the Most Region (Československá armáda Mine) and Sokolov Region (Jiří Mine) and processed to obtain a required grain size. The samples were pyrolyzed in a closed tube reactor at 900°C (5°C/min, holding time of 30minutes), and the resulting liquid product was collected. As the composition of the pyrolytic oils (content of aliphatic and aromatic hydrocarbons, alcohol, and functional groups) is analogous to that of a conventional flotation agent (in this case Montanol 800), the oils were used in a flotation process to float black coal slurry from the Karviná Region (from Lazy Mine and a settler of DarkovMine). The pyrolytic oils were applied in a mix with Montanol 800 in a dose of 500 g/t, and the individual proportions of the agents differed from 1:4 to 5:0 (pyrolytic oil:Montanol 800). The final values, i.e. concentrate yields and ash con
