ore dressing for minerals on earth

  • Ore Minerals : What are Ore Minerals?Geology Page

    An ore is a natural occurrence of rock or sediment which contains enough minerals with economically important elements, typically metals, that can be extracted from the deposit economically. The ores are extracted by mining for a profit from the earth; they are then refined often by smelting in order to extract the valuable elements.

  • What are Ore Dressing MethodsMinerallurgy

    The gravity separation process is used to separate ore minerals. It is an old dressing technic for ore concentration. The concentration is achieved either by gangue removing or valuable minerals recovering. It is mostly applicable for coarse liberated ores, and it has significant economic and environmental benefits, Gravity separation:
