Metallurgy

Based on real world metal ores, and their use - BUT changed to suit me :) Even so these are just notes, and won't hold for every single site.

Metal Ores

PPM = Parts per Million of the earth's crust. High numbers mean higher frequency.

Metal	Notes	PPM
Iron	One of the world’s most common metals - found just about everywhere. Frequently mined in single metal sites by humans. (add carbon to make steel) weapons, armour - Other uses include cooking pots, hinges, hardware etc. tailings are also high in other useful metals such as copper, nickel, and cobalt.	Gem Stone = Hematite	56300
Zinc	Common co-products in zinc ores include minerals of lead and silver. Other mines may produce zinc minerals as a by-product of the production of ores containing more valuable minerals or metals, such as gold, silver or copper. t he element is normally found in association with other base metals such as copper and lead in ores Worldwide, 95% of new zinc is mined from sulfidic ore deposits, in which sphalerite (ZnS) is nearly always mixed with the sulfides of copper, lead and iron. Main Ore = sphalerite (can be Gem quality - red stone)	70
Copper	A common metals. Used for coins, common jewellery, cooking pots, Mugs, plates etc. – and a core component of Bronze.	60
Lead	often found in association with Silver. (ore = Galena) used for Sling Bullets, water pipes, shielding from magic/scrying, coffins, malleability, water resistance, stained glass. (etc) The main lead-bearing mineral is galena (PbS), which is mostly found with zinc ores. Arsenic, tin, antimony, silver, gold, copper, bismuth are common impurities in lead minerals. Other minerals in association are sphalerite, marcasite, chalcopyrite, cerussite, anglesite, dolomite, calcite, quartz, barite, and fluorite.	14
Tin	Mix it with Copper to make traditional bronze, however it is a fairly rare metal - makes Zinc more important. Gems associated with Tin mines include tourmaline, topaz,	2.3
Silver	Not as common as Copper, not more common than gold. Often found in association with lead. Other sources of silver are the ores of copper, copper-nickel, lead, and lead-zinc. Uses: average jewellery, small plaques/decoration/statuary etc (alloyed with copper to make sterling silver – it can be used for instruments, vases etc etc)	0.075
Gold	coins, expensive jewellery, small plaques/decoration/statuary etc. Gold ore dumps are the source of many heavy elements such as cadmium, lead, zinc, copper, arsenic, selenium and mercury.	0.004
Bronze (alloy)

Bronze (of any sort) is hard enough for weapons and armour, but with a risk of breaking - however, this isn't too much of an issue with arrow, bolt, spear, javelin, darts heads :). Other uses include cooking pots, hinges, hardware etc.||

Q =Quartz - is not particularly associated with any metals. Place just about anywhere.
