Fundamental Study of Palladium Recycling Using "Dry Aqua …
In this research, a recycling process for palladium using "dry aqua regia," which consists of iron(III) chloride–potassium chloride, was proposed. Palladium was dissolved in "dry aqua regia," and the dissolved palladium was recovered by leaching with potassium chloride solution with added ammonium chloride and nitric acid. Palladium …

In an attempt to prepare a concentrate high in platinum and palladium values and low in gangue minerals, tests were made to investigate the use of a water-soluble polymer (Hercules Minflo I) gangue depressant in the rougher circuit. By using 0.06 lb Minflo I per ton of ore, concentrates containing 2.4 oz/ton Pt and 12.3 oz/ton Pd were prepared.

Methods of recovering platinum-group metals from Stillwater Complex ore
Because the ore is sulfidic in nature, it was concentrated by froth flotation. A 45 kg/h process development unit (PDU) was constructed and 85 to 95% of the platinum and palladium were recovered from the ore by using mercaptobenzothiazole or sodium isobutyl xanthate as collectors.
