Machining Precious Metals In The Loupe

Jul 01, 2019 Generally, only gold and silver are used in their purest form as the platinum group metals are alloys that consist mainly of platinum (with a smaller composition of Ru, Rh, Pa, Os, Ir). Precious metals are notable for being extremely dense and having a high melting point, which make them suitable for a variety of applications.

Platinum group Wikipedia

The platinum-group metals (abbreviated as the PGMs; alternatively, the platinoids, platinides, platidises, platinum group, platinum metals, platinum family or platinum-group elements (PGEs)) are six noble, precious metallic elements clustered together in the periodic table.These elements are all transition metals in the d-block (groups 8, 9, and 10, periods 5 and 6).

Silver Mining and Refining Education

Modern Silver Mining. Even these ores are found in small quantities, and many tons of material must be mined to produce just a few ounces of silver. At least 80 percent of the world’s silver is produced instead as a by-product of mining for other metals such as gold, copper, lead, zinc, and uranium. Primary and secondary sources of silver ore.
