Abstract
It is possible to forecast efficiency of mechanical activation of loparite concentrate to make it subsequent nitric-acid leaching fast using the X-ray crystal analysis data. It is found that the type of accumulated energy influences the energy of activation and reactivity of loparite. The authors suggest an expression to estimate extraction of rare earth elements in nitric-acid solution versus energy of structural changes caused in loparite by mechanical activation and leaching.
