In the last decades, a worldwide investment in the recovery or substitution of platinum group metals (PGMs) has been financed. during the mining process, compared to 15% of overall processing. Be-The Platinum Standard 2022 published by Heraeus [19] shows that recycled PGMs can only meet 27 %–33 % of the gross demand for PGMs. The gap must be filled with mining supplies, as shown in Table 1. >95 % of the PGMs mining supplies are from South Africa, Russia, Zimbabwe, and North America, meaning that other countries Platinum group metals recycling from spent automotive

Hazards identified and the need for health risk assessment in
Mining and processing of minerals also result in occupational exposure to toxic substances such as platinum, chromium, vanadium, manganese, mercury, cyanide and diesel particulate. South Africa has set occupational exposure limits (OELs) for some hazards, but mine workers are still at a risk.With platinum prices declining due to a seismic demand shift and firms grappling with the high cost of labor and prolonged production-stopping labor strikes, the financial sustainability of platinum group metal (PGM) firms has come under duress since 2012. This article seeks to understand how mining firms have reshaped their strategies Firms’ approach to mitigating risks in the platinum group

Simplified platinum group metal (PGM)
The capital investments to process PGMs from flotation concentrate are very large and a significant barrier to entry for smaller mining companies [15]. Platinum producers evaluate process routesAbstract. The necessity, economics, and sustainability of recycling platinum-group metals (PGMs) from spent automotive catalysts (SAC) have stimulated the emergence of many relevant treatment technologies. Considering the industrial feasibility and recovery efficiency of smelting, this study provided an in-depth review of smelting Recycling of platinum-group metals from spent

Recovery and extraction of platinum from spent
South Africa, as the major mining supplier of platinum, has always insisted on producing this metal from the mine and primary sources. In this process, platinum is completely recovered [29]. In leaching with 1 M oxalic acid, 5.58% of platinum is extracted at 60 °C for 10 hr. 19.72% of Platinum is recovered under similar conditions to theOne study calculated the crystalline silica content of crushed stope rock samples from two platinum mines as 0.45%, compared with 9.9 and 39.1% in two gold mines (21).
