If any of you are like myself and needed a cheat sheet for the metallurgical terms here it is (for copper at least).
Note I'm not at all sure on the rules of referencing here... but can't help but to do my day job per se.

Hope this helps us all follow whats being said in some of these posts rather than just thinking.... Yess Chalcocite is good right?

I'm of two minds right now, but lets leave that off the table for the moment and focus on helping understand the nomenclature of these materials.


For reference I've highlighted the commonly thrown around terms which I have seen in these forums and added in a few myself to fill the table out
