摘要：Coal preparation currently has a number of significant
problems concerning the dewatering processes (water purification, coal
sludge thickening). These processes polymeric flocculants are used to their
enhancement. To select a floculant for its further use at the preparation
plant is currently a quite complicated and mainly empirical process. The
authors have conducted research in order to establish a possibility to
recommend certain flocculants to be chosen based on the properties of coal
pulp, that were established during the experiments, and the properties of
the aforementioned flocculants. In this paper are listed the methods, that
were used during the research, the results of the laboratory tests of anionic
flocculants Magnaflock, that were conducted on various coal pulp samples
with various properties. The industrial testing of the selected flocculant at
the coal preparation plant “Anzherskaya” was examined in detail. After the
analysis of the obtained results certain conclusion was conducted.
