Limonite. Limonite is a hydrous iron oxide ore, which is formed after the weathering of other ores, and is the most widely distributed in nature, but it is rare to find a large amount of ore deposits. Its chemical formula is nFe2O3·mH2O (n=1～3, m=1～4). Limonite is actually a mixture of goethite (Fe2O3·H2O), hydrogoethite (2Fe2O3·H2O) and ...

Palladium element extraction method - Deep underground mining technique
Since it is lighter than platinum and similar to gold, palladium can be made into a 100 nm thin form. White gold is prepared as an alloy of gold with one of three metals: nickel, silver and palladium. The palladium and gold alloy is more expensive compared to nickel and gold, but that can result in an allergic reaction rarely.
