PLATINUM-GROUP METAL RECOVERY METHOD, COMPOSITION CONTAINING PLATINUM-GROUP METALS, AND CERAMIC MATERIAL

摘要

Provided is a platinum-group metal recovery method for efficiently recovering platinum-group metals. The platinum-group metal recovery method comprises an immobilization step for bringing a raw material melt containing platinum-group metals, an alkali metal carbonate or hydroxide melt, an oxide melt, and a ceramic material into contact with each other to immobilize the platinum-group metals on the ceramic material.
