Ore minerals in IOCG deposits are typically copper-iron sulfide chalcopyrite and gangue pyrite, forming 10–15% of the rock mass. Supergene profiles can be developed above weathered examples of IOCG deposits, as exemplified by the Sossego deposit, Para State, Brazil , where typical oxidised copper minerals are present, e.g.; malachite ...
Green liquid with symbol Ar and atomic number 7. Makes a compound that is corrosive to copper when mixed with Galine and Sanite, and a compound that produces clouds when exposed to air when mixed with Regalite. The real element 7 is nitrogen; and Ar = argon. Atium Mistborn: Metal. Forms the body and power of the shard Ruin. If an Allomancer ...
Resources of the deposit are 152.8 Mt at 1.18% Cu, 0.48 g/t Au and 2.92 g/t Ag plus 38.3 Mt at 1.17 g/t Au of non-sulfide ore. [ 9 ] In contrast to the Olympic Dam deposit, an iron oxide copper gold deposit of similar age about 200 km to the southeast of Prominent Hill, uranium values do not exceed 150 ppm and therefore uranium recovery is not ...
This is a list of named alloys grouped alphabetically by the metal with the highest percentage. Within these headings, the alloys are also grouped alphabetically ...

Because the primary ores of cobalt always contain arsenic, smelting the ore oxidized the arsenic into the highly toxic and volatile arsenic oxide , adding to the notoriety of the ore. [ 65 ]
