• What is Mineral Processing? with pictures

    There are four main types of mineral processing, each of which uses a different method to separate valuable materials from ore gangue. The four different methods involve the reduction of ore particle sizes, the separation of particles by size, concentration of wanted minerals, and the removal of liquids from the solid minerals.

  • Extractive MetallurgyIntroduction to Chemistry

    An ore is a type of rock that contains minerals with important elements such as metals. Ores are extracted through mining; they are then refined to extract the valuable elements. The grade or concentration of an ore mineral, or metal, as well as its form of occurrence, will directly affect the costs associated with mining it.
