| Abstract: | The reaction of nickel(II) and copper(II) sulfate solutions with carbonate flour prepared from carbonatite was simulated thermodynamically and studied experimentally. The conditions under which open systems and those isolated from the atmosphere attain stationary state (carbonatite consumption and grain size, pH of the medium) were determined. The ionic and mineral composition of new formations and the theoretically possible degree of purification were found. |
