Essay

It was investigated influence of sodium, magnesium, iron and chromium lignosulphonates on colloid-chemical and rheological properties of higly concentrated slime-coal hydrosuspensions. It is found an optimal granulometric composition of the solid phase and effective concentration of dope for preparation of time-stable higly concentrated hydrosuspension. It is studied the dependence of rheological parameters of higly concentrated slime-coal hydrosuspensions on concentration of the solid phase and dope, temperature and others. For the first time the hydrosuspensions of slime-coal and magnesiumbisulphite lye has been studied and the solid phase mass concentration of 75 % was achieved.
