Metals, Metallurgy, Materials and Mining
Material science plays a important role in metallurgy too. Powder metallurgy is a term covering a wide range of ways in which materials or components are made from metal powders. They can avoid, or greatly reduce, the need to use metal removal processes and can reduce the costs. Pyro metallurgy includes thermal treatment of minerals and metallurgical ores and concentrates to bring about physical and chemical transformations in the materials to enable recovery of valuable metals. A complete knowledge of metallurgy can help us to extract the metal in a more feasible way and can used to a wider range. Global Metallurgy market will develop at a modest 5.4% CAGR from 2014 to 2020.
The extraction of valuable minerals or other geological materials from the earth is called as Mining, where as Metallurgy is the field of Materials Science that deals with physical and chemical nature of the metallic & intermetallic compounds and alloys. Different techniques and technologies used in the extraction and production of various metals are extraction of metals from ores, purification, casting, plating, spraying, etc. in the series of processes, the metals are subjected to thermogenic and cryogenic conditions to analyze the corrosion, strength & toughness and to make sure that the metal is creep resistant. In 2015, Global Ore mining industry performance has been weak due to falling iron ore prices and stagnating demand from emerging markets. However, industry performance is expected to improve over the five years to 2020, with revenue expected to rise.
