Optimalizace podmínek flotace černouhelných kalů

Abstract

The diploma thesis deals with optimalization of floatation of bituminous coal slurries, with an emphasis on dosing of floatation agents. It can be divided in two parts. The first part – chapters 2 to 7 – is theoretical. It deals with characteristics of coal, bituminous coal and coal slurries and briefly describes the process of flotation, the factors that influence it, floatation agents and floatation machines. The second part, chapter 8, is experimental and describes the realized tests and their results. The author observes mainly the influence of floatation agents´ dosing on ash content in the concentrate and then on yield and efficiency of floatation process.
