Molybdenum - Wikipedia

Molybdenum is a chemical element with the symbol Mo and atomic number 42. The name is from Neo-Latin molybdaenum, from Ancient Greek Μόλυβδος molybdos, meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of other metals ...

Ore enrichment | KGHM Corporate Website

A mechanical process of copper ore enrichment is essential for effective smelting. The concentration level obtained at the enrichment stage makes the copper material fit for further processing at the smelter. This processing is required due to the fact that the copper ore deposits mined by KGHM in Poland contain, on average, only 1.52% of copper.

what do you mean by enrichment of ores ? | Yahoo Answers

Jul 24, 2007· Enrichment of ores means increasing the metal (or non-metal) content of an ore by removing as much of the minerals in the ore that do not contain the desired substance. This can be done by several means including screening, gravity separation, magnetic separation and fine grinding followed by froth flotation; to concentrate the metal-rich ...

Uranium processing | Britannica

Uranium processing, preparation of the ore for use in various products.. Uranium (U), although very dense (19.1 grams per cubic centimetre), is a relatively weak, nonrefractory metal. Indeed, the metallic properties of uranium appear to be intermediate between those of silver and other true metals and those of the nonmetallic elements, so that it is not valued for structural applications.

Porphyry copper deposit - Wikipedia

Porphyry copper deposits are copper ore bodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the deposit itself. Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its name. In later stages, circulating meteoric fluids may interact with the magmatic ...
