to waste, to destroy, our natural resources, to skin and exhaust the land instead of using it so as to increase its usefulness, will result in undermining ... (60 mines) and platinum-group metals. Mining alone generates 8% of South Africa's gross domestic product (GDP). Figure 4. Mineralization zones associated with geologically recent ...
In the US, more than 4.6 million tons of electronic waste were disposed of in American landfills in 2000 ("Where Does E-Waste End Up?"). Such material has potential to provide a new supply for declining supplies of metals such as the platinum group elements and rare earths, both of which are found frequently in electronic products.
All of the platinum- group metals are valued for their corrosion resistance and their catalytic activity.1 According to the U .S. Bureau of Mines, ore containing the platinum-group metals is mined, concentrated, and smelted in Montana. The resulting platinum-group matte is sent to Belgium to be refined and separated.
Jeweler's Waste. Grindings, bench sweeps, polishing sweeps, floor sweeps, etc. ... There are several standard precipitants, different precipitants for different platinum group metals. Refining by this method is tricky and the purity of the resultant platinum group metal is often below normal standards. Refining of platinum metals is best done ...
Platinum is very effective at converting emissions from the vehicle's engine into less harmful waste products. ... Johnson Matthey perfected the techniques of separating and refining the platinum group metals and in 1879 Matthey produced a standard metre measure made of a platinum and iridium alloy.

Platinum Mining in South Africa. Platinum mining in South Africa, or mining for Platinum Group Metals (PGM), is widespread on the African continent, and South Africa holds over 80% of the world's reserves. For investors interested in the PGM sector in Africa, South Africa seems to be the logical starting point.
It is a specialty material group that focuses on recovering gold and silver, PGMs (palladium, platinum, rhodium, iridium and ruthenium), special metals (selenium, tellurium and indium), secondary metals (antimony, tin, arsenic and bismuth), and the BMs (copper, lead and nickel) from various residues including e-waste.
In recent years there is a notable increase in the interest in recovery of platinum group metals (PGMs), like: palladium, platinum or rhodium from waste electronic and electrical equipment (WEEE ...
The management of fission-produced platinum group metals (PGMs) from spent nuclear fuel, namely ruthenium (Ru), rhodium (Rh) and palladium (Pd), has been developing as a topic of research throughout the history of nuclear chemistry.
alchemy. In this manual are disclosed the methods used to recover platinum group metals (PGM`s) from scrap automotive catalytic converters (C/C`S). Most people know that C/C`s contain platinum; it's fairly common knowledge that in some mysterious way, the metal reacts with exhaust emissions, and purifies them, and so the planet will
The 2002 European Waste Catalogue and the Hazardous Waste List Hazardous Waste Classification Tool Hazardous Waste Classification Worksheet. It will be updated in the event of further amendments to the law and when the European Commission concludes its …
South Africa has more than 80 per cent of the world's platinum reserves, and is the world's largest producer of platinum group metals (PGMs). ... All waste gases, from driers, furnaces, and converters, are treated in a Lurgi radial gas scrubber (installed in February 1999) prior to disposal. ...
Copper, Nickel, and Platinum Group Metals The DULUTH COMPLEX Hosting World Class Copper, Nickel, and Platinum Group Metal Resources Exploring since 1948 There are many deposits of copper, nickel, and Platinum Group Metal (PGM) resources in the bedrock along approximately 40 miles of the edge of the Duluth Complex near Babbitt, Minnesota. This
Precious Metal Recovery from Low Concentration Solvent Waste Streams in the Pharmaceutical Industry. Homogeneous catalysts are often thought to be uneconomical to extract from liquid waste streams, especially at low concentrations in solvents, due to the difficult nature of the extraction and the traditional high costs of the recovery process.
They regarded platinum as an unwanted impurity in the silver they were mining. The catalytic properties of the six platinum group metals (PGM)– iridium, osmium, palladium, platinum, rhodium, and ruthenium – are outstanding. Platinum's wear and tarnish resistance …
Platinum and platinum group elements can be recovered with relatively high efficiency from the catalytic converters of hybrid car engines, and to a lesser extent, from chemical catalysts and glass. In the past decade, catalytic converters containing platinum can be recovered for at least 99.8% of their functionality due to the easy removal of ...
Platinum Group Metal Recovery from Spent Catalytic Converters . The catalyst component of a catalytic converter is usually platinum (Pt), along with palladium (Pd), and rhodium (Rh). All three of these platinum group metals, or PGMs, are extremely rare but have a broad range of applications in addition to catalytic converters.
