Hey! I'm from a country without a chat so it's hard for me to find friends. Is there any discord server or roblox place where I could find people to play with? Generally or specific (Rise of Nations)

Hey guys! Interested in process of getting 100% copper. In particular from chalcopyrite. Tried reading wiki and other sources, but can't quite grasp it. Can someone explain it to me, chemical and physical processes, machines and such. No need to be precise, just easy to understand
