“…Руды металлов платиновой группы обрабатываются различными методами предварительного обогащения в соответствии с их текстурными и минералогическими характеристиками. Руды PGM обрабатывались с использованием технологии, включающей механическое обогащение, высокотемпературное плавление, первичную обработку и гидрометаллургическую переработку [58,59].…”

Platinum group metals (PGM) are widely used in catalytic industry due to their outstanding physical and chemical properties (high-temperature stability, high catalyst activity, high heat resistance, high corrosion resistances). They are used in medical fields, electronics, oil refining, production of ammonia, fuel cells, automotive industry. Catalytic wastes are an important secondary source of metals because recycling of wastes is more economical and ecological way of metals obtaining compared to mining from ores. Spent automotive catalyst is a rich source of platinum group metals [PGM: platinum (Pt), palladium (Pd), and rhodium (Rh)] which contains higher concentrations of PGM than found in natural ores. This review presents the analysis of the recovery methods of platinum group metals from spent catalysts and their advantages and disadvantages. As a result, all methods were analyzed and the most promising (most environmentally friendly and economical) was pointed out.

“…Rhodium recovery also tends to decrease if sinter hydrochlorination time reduces as rhodium has a tendency to exist in many different complex forms such as [RhCl6] 2and [RhCl6-x(H2O)x] x-3 which do not get sorbed easily. In general, recovery of PGMs is found to increase when a two-stage leaching in counter current mode is employed [19]. Nitrogen sorbents generally are nowadays preferred for PGM recovery from solutions due to their high absorption and good kinetic properties.…”

Rhodium is a rare and highly expensive metal with widespread and diverse industrial applications. This makes rhodium recovery and recycling extremely important. Various processes and methods have been developed for rhodium recovery which are very specific to the nature of the application of rhodium. This research study aims at providing a brief yet holistic, classified overview of the many methods that are being employed over the last few decades for rhodium recovery at both laboratory and industrial scale. Specifically, the focus is on the processes employed for recovery of rhodium from waste water, radioactive waste, catalysts, scrap and by leaching with the objective of facilitating a better understanding of such methods. This research study enables researchers to better understand the various processes employed in rhodium recovery.

“…However, the solution concentrations of PGMs for the Kell process tend to be lower. According to Liddell et al (2010) and Tatarnikov et al (2004), the technology is insensitive to the chromite content in the feed. As depicted in Fig.…”

“…Thiourea has long been known to form extractable complexes (its involvement in elution/stripping processes) with both platinum and palladium (Schoeman et al, 2012;Dunne et al, 2009;Tatarnikov et al, 2004;Green et al, 2004). However, it would seem that no work has been conducted on leaching PGM ores/concentrates using thiourea as no literature could be found.…”
