Which non-metallic element is obtained via the 'Frasch Process'?
Frasch process Frasch process The Frasch process is a method to extract sulphur from underground deposits. It is the only industrial method of recovering sulphur from elemental deposits. Most of the world's sulfur was obtained this way until the late 20th century, when sulfur recovered from petroleum and gas sources became more commonplace (see Claus process). In the Frasch process, superheated water is pumped into the sulphur deposit; the sulfur melts and is extracted. The Frasch process is able to produce high purity sulfur. The Frasch sulfur process works best on either salt domes or bedded evaporite deposits, where sulfur is found
Non-metallic inclusions structure and amount of non-metallic inclusions in steel and alloys with high accuracy. Non-metallic inclusions Non-metallic inclusions are chemical compounds and nonmetals that are present in steel and alloys. They are the product of chemical reactions, physical effects, and contamination that occurs during the melting and pouring process. These inclusions are categorized by origin as either endogenous or exogenous. Endogenous inclusions, also known as indigenous, occur within the metal and are the result of chemical reactions. These products precipitate during cooling and are typically very small. Exogenous inclusions are caused by the entrapment of nonmetals. Their size varies greatly and
