Precious Metals / Rare Earths - NETZSCH Grinding & Dispersing Precious Metals and Rare Earths In addition to gold and silver, platinum metals such as mercury and rhenium are also counted among the classical precious metals. At room temperature in air, these elements either do not corrode at all or do so extremely slowly and to a very slight degree.

Therefore, rare earths recovered from waste residue would reduce the demand of rare earth elements from primary sources. In this study, the feasibility of recycling rare earths through a hydrometallurgical process was investigated. The selective leaching of Nd from grinding sludge can successfully raise the rare earths concentration to 70%.
