摘要：
Effect of raising in the range 75-95 degrees C the temperature at which hydrated lanthanide phosphates are synthesized on the degree of their chemical activity and, accordingly, on specific features of the sulfuric acid leaching was studied. The mechanism of restoration of the chemical activity of lanthanide compounds was considered.
