Studies of the sorption capacity towards Cu2 ions of diatomite from the Ghidirim location of RM, as well as of the extracted clay phase are presented. Separated clay fraction from diatomic material is clean enough, and especially is rich in montmorillonite. Maximum sorption capacity for studied clay fraction is achieved by rising the temperature of calcination treatment up to 200o C. At higher temperatures the lattice of montmorillonite is contracted and its sorption capacity towards Cu2 ions decreases strongly.
