Wyoming beontonite saturated with Ca and Mg at five different ratios was equilibrated with NaCl solution. It was found that the preference of the bentonite for Ca over Mg was not affected by the presence of exchangeable Na. The separation factor of the bentonite equilibrated with NaCl was compared to that of bentonite in which alkaline earth carbonates and magnesium hydroxide precipitated. Precipitation of the carbonates caused a different distribution of the exchangeable ions in the bentonite crystallite compared to the distribution in the absence of precipitation. Where carbonates precipitated, Na was found between the interlayers and Ca and Mg occupied the outside surfaces of the clay.
