Precious Metal Refineries

Scrap and waste recovery and refining was and continues to be a vital part of their manufacturing process. The increasing use of expensive Platinum Group Metals (platinum, palladium, rhodium, rhenium, iridium and osmium) or PGMs in industrial products created a need to develop processes to recover these precious metals from scrap.

Processes

An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

To recover Pt, the PGMs present in the ore as their sulfides, arsenides or tellurides are concentrated by physical beneficiation followed by pyro/hydrometallurgical processes (Seymour and O'Farrelly, 2006). The concentrate is then leached in aqua regia to produce a leach solution containing Pt and other precious metals, such as Au, Ag, Pd and Rh.

Palladium Refining Tutorial

Palladium (Pd) refining can be a daunting task, similar to the other Platinum group metals (PGM's) refining process. This is mainly due to their similar (but different) physical and chemical properties. Separating Palladium from base metals and especially from sister PGM's, is rarely achieved completely in one refining cycle.
