Abstract
Experimental data on the dissolution of calcite in water and in the solution of sulphuric acid were treated with the help of the generalized equation of heterogeneous kinetics. The possibility of using this method to determine the kinetic characteristics of the process was demonstrated. The data on the limiting stage were obtained; rates constants of calcite dissolution under different conditions were calculated.
A procedure to calculate technological parameters of the process leading to a decrease in the level of acidation of natural water was proposed.
