This is a list of minerals which have Wikipedia articles.. Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species.
This list includes those recognised minerals beginning with the letter M.The International Mineralogical Association is the international group that recognises new minerals and new mineral names; however, minerals discovered before 1959 did not go through the official naming procedure, although some minerals published previously have been either confirmed or discredited since that date.
The part of an ore that is not economically desirable and that cannot be avoided in mining is known as gangue. [2] [3] The valuable ore minerals are separated from the gangue minerals by froth flotation, gravity concentration, electric or magnetic methods, and other operations known collectively as mineral processing [5] [7] or ore dressing.

This is a list of Latin words with derivatives in English language. Ancient orthography did not distinguish between i and j or between u and v. [1] Many modern works distinguish u from v but not i from j. In this article, both distinctions are shown as they are helpful when tracing the origin of English words.

The decision to bowdlerize the OSPD's third edition by removing a large number of possibly offensive words necessitated a separate, unabridged word list for tournament use. The first edition of OWL was created by the NSA Dictionary Committee, chaired by John Chew , and took effect on March 2, 1998.
Bornite, also known as peacock ore, is a sulfide mineral with chemical composition Cu 5 Fe S 4 that crystallizes in the orthorhombic system (pseudo-cubic). It is an important copper ore. It is an important copper ore.
Tin mining knowledge spread to other European tin mining districts from the Ore Mountains and evidence of tin mining begins to appear in Brittany, Devon and Cornwall, and in the Iberian Peninsula around 2000 BC. [2] These deposits saw greater exploitation when they fell under Roman control between the third century BC and the first century AD. [4]
Many automatic sprinklers, electric fuses, and safety devices in fire detection and suppression systems contain the eutectic In 19.1-Cd 5.3-Pb 22.6-Sn 8.3-Bi 44.7 alloy that melts at 47 °C (117 °F) [19] This is a convenient temperature since it is unlikely to be exceeded in normal living conditions. Low-melting alloys, such as Bi-Cd-Pb-Sn ...
