    Extraction of Metals (Metallurgy) – Overall Science

    Oct 09, 2020 Oct 09, 2020 The extraction of the metals from the calcined or roasted ore consists of two steps i.e., removal of earthy impurities and reduction of the ore to metal. The different methods applied for carrying out the concentration of ores are useful to separate only a part of gangue and the ore still contains some earth impurities

    Methods of extraction Many metals are found in the Earth's crust as ores. An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more difficult it is to

    On the other hand, carbonated metal ores are heated in a vacuum for easy extraction of metals. This is called calcination. This is how a concentrated ore is again refined to gather purer metals. This is a gist of how the extraction of metals ores and minerals is performed based on the physical and chemical properties of the impure ores

    The basic extraction of metals from ores has the following steps. 1. Grinding and Crushing. The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers. It helps to increase the surface area of the chunks for better chemical actions later. In technical terms, it is called pulverization

    Extraction of metals. There are two types of mines to obtain metals: Surface mining that is used when the mineral is near the surface. Underground mining that is used when the mineral is deep below the surface. It's used excavators, drills, explosives for extracting minerals from the rock.The minerals are separated into ore and gangue
