The largest use of palladium today is in catalytic converters. Palladium is also used in jewelry, dentistry, watch making, blood sugar test strips, aircraft spark plugs, surgical instruments, and electrical contacts. Palladium is also used to make professional transverse (concert or classical) flutes.
Palladium jewelry items: This can include rings, chains, bracelets, jewelry scrap. Palladium catalysts: Palladium can be found in automotive catalysts, industrial catalysts, palladium foil catalysts, petroleum refining catalysts. Palladium resins: These are chemicals used in manufacturing processes.
Palladium has been found uncombined in nature, in Brazil, but most is found in sulfide minerals such as braggite. It is extracted commercially as a by-product of nickel refining. It is also extracted as a by-product of copper and zinc refining.
Palladium is contained in most microprocessors and printed circuit boards. Platinum is used to make fiberglass, liquid-crystal display (LCD) glass and flat-panel displays, and cathode ray tubes.

Palladium was present in most food groups above the LOD of 0.0003 mg/kg with the highest concentrations found in nuts (0.003mg/kg), bread, offal, and fish groups (all 0.002mg/kg).
Palladium is generally found only in pure form, and along with platinum is found in sulfide concentrations in mafic igneous rocks It is mined in Russia, the USA(Montana), Zimbabwe, Australia, Canada and Finland.
Use a Magnet
Palladium isn't magnetic. If the piece you have is a forgery, it may contain iron. This is because iron is an inexpensive metal that's relatively easy to mold and shape. If your piece contains any amount of iron, it will react to a magnet.
Palladium is not magnetic, so it should not be attracted to a magnet. Using a strong neodymium magnet, you can check if the item is attracted to the magnet. If it is not attracted, it may be palladium, but this test alone is not conclusive, as other precious metals like gold and platinum are also non-magnetic.
Procedure-To 5 ml of a feebly acid solution add 4 or 5 drops of the P-nitrosodiphenyl- amine reagent. Development of a red-to-purple colour indicates the presence of palladium. If the colour is masked by that of the solution itself, extract with 5ml of ethyl acetate or chloroform.
Jewelry boxes and dresser drawers, where small, easy-to-overlook small pins, forgotten coins, and bits of jewelry can contain gold, silver and platinum. Kitchen drawers and storage areas, where pieces of silver tableware could be intermixed with other items.
Mobile phones contain many valuable metals and uncommon earths. An average iPhone contains around 0.034g of gold, 0.34g of silver and 0.015g of palladium. This is in addition to 1000th of a gram of platinum.
Russia and South Africa are the two largest palladium-producing countries in the world, and both are known for their rich mineral reserves.
Rhodium is used for several different things, such as automobiles, jewelry, searchlights, electronics and mirrors.
Palladium compounds are encountered relatively rarely by most people. All palladium compounds should be regarded as highly toxic and as carcinogenic. Palladium chloride is toxic, harmful if swallowed, inhaled or absorbed through the skin. It causes bone marrow, liver and kidney damage in laboratory animals.
Jewelry factories that repair or produce platinum jewelry can be a great source of platinum scrap. Often, it can be found in floor dust, bench sweepings, and “squiggles” that are made when platinum is produced on machinery.
80% of the world's current production comes from South Africa and the Sudbury Basin of Canada. Smaller reserves can be found in the United States, Zimbabwe and Australia. Platinum is also attained through recycling.
The atomic structure of these metals means they can bond easily with other elements. Platinum is commonly known for being used in the manufacturing of jewellery but its main applications spread to catalytic converters, electrical contacts, pacemakers, drugs and magnets.
Palladium is also a critical input for certain stages of semiconductor manufacturing. It is primarily used in the metal connections attaching chips to circuit boards and in the junctions between the chips and other metals.
Currently palladium is the metal used in petrol vehicle catalytic converters, with about 2-7 grams per unit, depending on the vehicle in question.
