The present invention provides methods for recovering metals, including rare earth metals, from mixed metals. An example is the recovery of metals from electronic waste. The method of separation is based on the inversion and/or lowering of the thermodynamic energy barrier by using one or more stressors applied at appropriate ratios to create lower energy points in the thermodynamic energy landscape of the mixed metals. Example stressors include a) a chemical stress, b) a mechanical stress, c) a thermal stress, d) and electromagnetic radiation and/or light stress, an interfacial stress, and/or a magnetic flux gradient stress.
