Studies on the sedimentation rates of insoluble metal carbonates showed that Zn2+ has a higher sedimentation rate of 5.10x10-2 s-1 while Ni2+ has the lowest sedimentation rates of 1.10 x10-3. The rate of sedimentation of the metal carbonates decreased in the order: Zn2+ > Cd2+ > Cu2+ > Co2+ > Ni2+. The order showed a decrease in the density of the carbonates and also correlated with the decrease in the mass (and particle) absorption coefficient of the metal carbonates.
