What''s the Difference Between Pyrite and Gold ...
· Although gold is pretty much odorless, pyrite has a faint smell — and it smells like rotten eggs. (Again, it''s loaded with sulfur.) But where things can get confusing is gold and pyrite sometimes turn up in the same deposits. Remember, Frobisher''s ore did contain some genuine gold — albeit a teeny, tiny amount.

Pyrite not detectable?
· The metals in mineral samples like pyrite rock are not concentrated enough to set off a detector. There is a huge difference in concentration between an ore and a refined metal or that metal in native form. A gold nugget would have to be a couple of grams for an E-Trac to find it from what I hear.
Pyrite | Minerals Education Coalition
Pyrite. Commonly called fool''s gold, pyrite is the Earth''s most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.

· Pyrite is the most abundant iron−sulfur mineral in sediments. Over geological times, its burial controlled oxygen levels in the atmosphere and sulfate concentrations in seawater. However, the mechanism of pyrite formation in sediments is still being debated. We show that lithotrophic microorganisms can mediate the transformation of FeS and H2S to FeS2 at ambient temperature if …

It depends on your ore type, liberation by size, operating conditions, i.e. pH, Eh, conditioning time, etc. I worked on a porphyry copper ore from Philippines before where I found that dithiophosphate worked better in depressing pyrite in the rougher stage. I experienced a copper-gold massive ore type where thionocarbamate seemed to work better.

Pyrite is the rarest and most valuable ore in Cataclysm. It sells from 5 gold to 10 gold depending on what realm you''re on and often sells best in stacks of 1. It''s currently used by Jewelcrafters to prospect rare and uncommon gems and is expected to become the source of epic gems later in Cataclysm (this is highly controversial).

Pyrite Ore is an addition from GregTech spawns in The Nether in veins approximately the same size as a vein of Coal Ore. Pyrite Ore was described by GregoriusT, the creator of GregTech, as having a "Gaussian distribution probability" meaning that some chunks will have Pyrite Ore everywhere whereas other chunks may have no Pyrite Ore whatsoever for a long distance.
Pyrite ore is the only uncomon quality ore in Cataclysm (as Titanium Ore in WotLK was) WotLK epic gems were introduced in 3.2.0 (I guess Cata epic gems will be introduced in 4.2.0 so there is a real chance, that Pyrite Ore will be their source)
