Selektivní flokulace černého uhlí

Abstract

I flocculate floating and refloating gangue in the thesis. I am also interested in the theory of selective flocculation, in the way this process works, in what ways it is influenced and in the conditions in which is the flocculation employed. The other part of the thesis is focused on the laboratory test of the sedimentation of floating and refloating gangue and on the comparison of speed by addition of flocculating and coagulating agents. I also compare the speed of sedimentation, the clarity of clarified water, the size and the amount of flocculants.
