Metal powders are finely divided or powdered metals used in fabricating sintered parts, thermal spraying, filling plastics, and other specialized applications.Powdered metals include most types of metals. Metal powders are used in powder metallurgy, which is the process of making metal parts and components by heating compacted powdered metals to just below melting.

Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are called alloys.Metallurgy is used to separate metals from their ore. Metallurgy is also the technology of metals: the way in which science is applied to the production of metals, and the engineering of ...
Metallurgical engineering is based on the principles of science and engineering, and may be divided into process metallurgy, which is concerned with extracting metals from their ores to make refined alloys, and physical metallurgy, which involves the shaping, alloying, heat treatment, joining, corrosion protection and testing of metals.
Fine Grinding Before Leaching. Unlike flotation, leaching appliions do not suffer as much from the same surface chemistry impacts from steel media. The use of steel media, however, can still be detrimental to a leaching process. When fine grinding pyritic concentrates of precious metals, it is common to follow the fine

Mineral processing: Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
Metallography is the study of a materials microstructure. Analysis of a material's metallographic microstructure aids in determining if the material has been processed correctly and is therefore a critical step for determining product reliability and/or for determining why a material failed.

After mounting, the specimen is wet ground to reveal the surface of the metal. The specimen is successively ground with finer and finer abrasive media. Silicon carbide abrasive paper was the first method of grinding and is still used today.
Möss spectroscopy has been successfully used in investigation of the gold compounds present in ores and the gold species which occur during the process metallurgy of this metal.
Metallographic etching is a chemical technique used to highlight features of metals at microscopic levels. By studying the character, quantity, and distribution of these different features, metallurgists can predict and explain the physical properties and performance failures of a given sample of metal.
