Numerous spent automotive catalytic converters (SACCs) are being produced annually owing to the increasing number of end-of-life automobiles. Although various methods have been proposed for recycling platinum-group metals (PGMs) and rare-earth-elements (REEs) from SACCs, most achieve low recovery ratios owing to the poor …

The U.S. imports approximately 90% of PGEs, mostly from South Africa and Russia. This deficit, coupled with the tremendous importance of PGEs to the United States, lands them on the critical minerals list. Fortunately, lidar can help improve the mineral's availability. The Stillwater Complex deposit was discovered in the 1970s.

There are 2-7 grams of palladium in a typical catalytic converter. However, the price of palladium fluctuates and so does the value of your catalytic converter. The best way to get an accurate estimate is to take it to a scrap yard and have them weigh it. The average price per gram of palladium is currently $60.85.

The rare earth amount accounts for about one-third of the magnet weight (Buchert, 2011; Wuppertal, 2014). In 2015, from a total production of about 78 000 tonnes of NdFeB (Benecki, 2013), it was estimated that the wind power sector required about 10% (Lucas et al., 2015). This would translate into an annual global consumption of rare …
