Iron ore

Iron ores[1] are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe Get price

Examples of Metal Ores

Platinum is the second-most valuable metal ore and is found in thin layers of sulfides. Being extremely rare, it is commonly found in microscopic amounts mixed in with other metal ores, and can be separated only by advanced processing, though it is also found in the very rare mineral sperrylite.

The Properties and Applications of Platinum

2020/8/21Extracting platinum from ore is both capital and labor-intensive. It can take up to 6 months and 7 to 12 tons of ore to produce one troy ounce (31.135g) of pure platinum. The first step in this process is to crush platinum containing ore and immerse it in the reagent containing water; a process known as 'froth flotation'. Get price

Platinum

Platinum is a chemical element with the symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal.

40d:Magnetite

Magnetite is one of only 3 types of stones that can contain native platinum. It is also the only metal ore to occur as large clusters (~750 pieces on average). Because of its high material value compared to other types of stone that occur in large quantities (and the fact that you're probably going to want to mine it out anyways), magnetite clusters make excellent sites for high- value rooms.
