In World of Warcraft, mithril and truesilver both appear; truesilver is a rare spawn node in the same areas as mithril. Both can be mined as ore and smelted into a bar using the mining profession. Mithril also appears in the MMORPG Guild Wars 2 as a blueish-silver metal used in crafting.
Galena is the main ore of lead, used since ancient times, [6] since lead can be smelted from galena in an ordinary wood fire. [7] Galena typically is found in hydrothermal veins in association with sphalerite , marcasite , chalcopyrite , cerussite , anglesite , dolomite , calcite , quartz , barite , and fluorite .
Wolframite ore exhibits massive form with a dark grey to reddish black coloration. [5] Wolframite in its pure crystal form exhibits a monoclinic crystal system with a perfect cleavage of {010} and an iron black color. Wolframite in its crystalline form also displays lamellar and prismatic habit. [10]
The difficulty of separating aluminium from oxygen in the oxide ores was overcome by the use of cryolite as a flux to dissolve the oxide mineral(s). Pure cryolite itself melts at 1012 °C (1285 K ), and it can dissolve the aluminium oxides sufficiently well to allow easy extraction of the aluminium by electrolysis .
[3] [4] As the grade of ores from terrestrial mines has decreased over time, ferromanganese nodules may offer a way to meet the growing global demand for rare metals. [4] However, the low estimated growth rate of hydrogenic nodules of about 2–5 mm per million years categorizes them as a non-renewable resource .
Baryte, barite or barytes (/ ˈ b ær aɪ t, ˈ b ɛər-/ BARR-eyet, BAIR-[7] or / b ə ˈ r aɪ t iː z / bə-RYTE-eez [8]) is a mineral consisting of barium sulfate (BaS O 4). [3] Baryte is generally white or colorless, and is the main source of the element barium.
The ores seen in this type of deposit have nodular texture and are loosely-packed nodules with a size range of 5–20 mm. Other minerals that are seen in podiform deposits are olivine , orthopyroxene , clinopyroxene , pargasite , Na-mica , albite , and jadeite .
