elements extracted during gold ore dressing

Mining Flashcards Quizlet

Subsurface mining removes coal and various metal ores that are too deep to be extracted by surface mining. It does not disturb the land as much as surface mining, produces less waste material, but leaves much of the resource in the ground and is more dangerous and expensive.

Mineral dressing (= Orebeneficiation)

Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate (enriched portion) containing most of the ore minerals and a tailing (discard) containing the bulk of the gangue minerals. Mineral dressing.
