Pyrite Ore
just prospected 100 obsidium and 80 pyrite - so 20 prospects and 15 respectively - looking for inferno rubies. from the pyrite i got 5 infernos, 2 amberjewels 5 other blues, 16 greens and 38 volatile earth. from the obsidium i got a buncha green stones - not 1 blue. so for value pay the g (around 7g apiece on Staghelm) and prospect pyrite.

The age of pyrite from the Novogodnee-Monto deposit is consistent with independent geological estimates for the age of ore formation (380–400 Ma). The pyrite U-Th-He ages are quite reproducible but show scattering within the range of 370–420 Ma, which may be explained by (1) the presence of excess 4 He, (2) the loss or input of U, Th …

Leaching of a pyrite-based ore containing copper using
The oxidation of sulfide-based ores is industrially relevant as it facilitates the extraction of valuable metals and eliminates undesired elements from an ore. Even though oxidation can be done thermally (pyrometallurgy), solution-based (hydrometallurgical) methods are currently sought as they represent a more sustainable option. Here, the …
