In simple terms, mineral processing is separating commercially valuable minerals or metals from other rocks. It’s not often that you dig up a large gold nugget. Instead, small particles of gold can be found mixed in with other minerals, metals, and rocks, some valuable, and some not. The collection of all these materials together is called ore.
