The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
Ball mill - A steel cylinder filled with steel balls into which crushed ore is fed. The ball mill is rotated, causing the balls to cascade and grind the ore. Banded iron formation - A bedded deposit of iron minerals. Basalt - An extrusive volcanic rock composed primarily of
May 30, 2020 While the ore you unearth is nice and hard, you cant do anything with it if it contains metal, dirt, and sand mixed into it. Not only does it make it difficult to build metal products of adequate quality, it is also difficult to produce even any results. Therefore, in order to use metal, a process in which pure metal is gained from ore is essential. This is where the Refining skill comes in ...
