Abstract
Hydrometallurgical methods are described for the isolation and recovery of platinum from rhenium-containing materials, and more particularly, from superalloys containing rhenium, platinum, and other metals. In addition, apparatuses capable of carrying out the hydrometallurgical methods and the product streams generated from the methods and apparatuses are described.
