Regenerative recycling of platinum group metal alloy scrap: There are many types of platinum group metal alloy scrap. In a few cases scrap alloy fixed point collection, the composition of the same, only in use by contamination, or physical state is destroyed and lost in use, only need to eliminate contaminants can be reprocessed for new devices reuse. High temperature oxidation to remove oil and carbon, boiling with hydrochloric acid, sulfuric acid or nitric acid to remove base metals, dissolving with alkali or hydrofluoric acid to remove silicon, etc. are all methods to eliminate physical contamination. In most cases the collected scrap alloys are of many sources and complex composition, and must be re-dissolved and transferred into solution - separation of impurity elements - separation of platinum group metals from each other - refining and other processes to obtain pure metal.
Recovery of Pt-Pd-Rh waste catalytic network.
Pt-Pd-Rh catalytic network is used in ammonia oxidation towers, the general composition of the ternary alloy Pt-4Rh-3.5Pd or binary alloy Pt-(5-10)Rh, China uses a quaternary alloy of Pt-Pd-Rh-M (M is another active metal) that increases the amount of Pd. Alloys are drawn into 0.06-0.09mm fine alloy wire woven into a mesh. Due to the high temperature oxidation conditions Pt, Rh oxidation volatilization of the fine wire surface to form a rough "cage", the strength is reduced and damaged, while the trace base metal contamination reduces the catalytic activity and scrapped, must be recycled and regenerated for use as a new net.
