Ore is natural rock or sediment that contains desirable minerals, typically metals, that can be extracted from it Ore is extracted from the earth through mining and refined, often via smelting, to extract the valuable element or elements The grade of ore refers to the concentration of the desired material it contains The value of the metal an ore contains must be weighed against the cost .
Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied The field is a materials science, covering all aspects of the types of ore, washing, concentration, separation, chemical processes and extraction of pure metal and their alloying to suit various applications, sometimes for direct .
Mining and Mineral Processing Metal deposits are mined in a variety of different ways depending on their depth, shape, size, and grade Relatively large deposits that are quite close to the surface and somewhat regular in shape are mined using open-pit mine methods (Figure 201) Creating a giant hole in the ground is generally cheaper than .
This method of concentration of the ore is based on the difference in specific gravities of the metallic ore and gangue particl Generally metal ores are heavier than the gangue associated with them By flowing the powdered ore in a current of water, the lighter rocky impurities can be washed away and the ore particles are left behind
