| Abstract | Studied were the processes of coagulation and precipitation of silica in the hydrothermal solution. Experiments were carried out on colloid silica coagulation and precipitation by various types of metal cations. Residual concentrations of silica and cations in the treated solution were determined, as well as pH and amount of Ca, Mg, Al and Fe in the settled material depending upon the coagulants consumption at 20?C and 96?C. Stability of colloid silica in hydrothermal solution was studied, as well as the mechanism of coagulation and precipitation of silica by metal cations. |
