The additions react with the iron oxide, causing it to form into a slag for removal. Once the iron is removed, the remaining Sulfur is oxidized and removed from the copper sulfide, yielding what is known as blister copper, due to its bumpy surface. Blister copper has a minimum copper content of 98.5%. Blister copper is refined to high-purity ...
Copper ore is an ore, which can be smelted in a furnace along with a piece of tin ore to create a bronze bar. Copper ore, along with tin ore, are the first ores a player can mine using the Mining skill, and has no requirements to mine. Mining one copper ore grants 17.5 Mining experience. After being mined, a copper ore rock takes approximately 2 …
