Nov 16, 2020· The results showed that the recovery of PGMs can reach over 90% when the diameter of the iron droplet was 0.1–0.3 mm at a temperature of 1500–1650°C for a reasonable smelting time of 1 h. Based on these findings, Dong et al. (2014) also studied the recovery of platinum from the waste catalyst using iron trapping based on solid state. In ...

Platinum group metals and gold, silver were together called the "precious metals". The platinum group metals has six elements such as platinum (Pt), palladium (Pd), germanium (Rh), iridium (Ir), Niu (Ru), osmium (Os) and so on. In addition, the content of platinum-group metals in the Earth's crust is very poor.
