The kinetic pulverizer can be selectively operated at specific speeds that serve to size reduce a majority (for example, between 70% and 100%) of the waste in a single pass (one pass kinetic pulverization) or selectively liberate a portion of the manufacturing waste product. Optionally, the process can include a separation stage, such as mechanical and/or magnetic screening.
The present document related to the processing of materials, such as ash waste, mining waste, consumer waste, or industrial waste, to separate valuable components. There is provided a process and system for extracting a valuable component, such as rare earth elements (REE) from a feedstock comprising REE-embedded material.
