Refining and Recycling High Purity Metals


Dr. Ruth Merrifield discusses the challenges faced in the refining process for elements used in the production of LEDs, semiconductors, solar applications, and rare earth permanent magnets. With gallium (Ga) as a case study, we learn how large sources can come from recycling, which require further processing, removal of contaminants and monitoring analysis to provide trend data, while confirming purity levels.
