ABSTRACT:
One aspect is a method of recovering minerals. The method includes heating aggregated minerals with microwave energy. The aggregated minerals consists of at least a first and a second mineral bound together, the first and second minerals each having different differential thermal expansion rates such that fractures occur between the minerals of the aggregated minerals. The fractured minerals are subjected to microwave heating to induce fractures between and separation of the at least first and second minerals, and also to ultrasound energy causing further size reduction. The fractured and size-reduced minerals are heated with microwave energy. The fractured and size-reduced minerals consist of metal-containing materials, such that metal-containing materials are heated to at least the melting temperature of one of the metals in the metal-containing materials.
