Beryllium | Minerals Education Coalition

Beryllium (Be) is a silverwhite and very light metal It has a very high melting point at 2349 °F (1287 °C) It is found in nature primarily as bertrandite, which is mined in Utah, or as beryl The combination of its light weight and high melting point makes it valuable for making metal alloys which are used in electronic and electrical components, aerospace, automobiles, computers, oil and gas drilling equipment, and

Mineral Processing an overview | ScienceDirect Topics

Mineral processing or mineral beneficiation or upgradation involves handling of three primary types of ROM ore material which has been blasted, fragmented and brought out from in situ position These materials can be used directly or by simple or complex processing and even applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods The categories are as follows:

Heat capacities and thermodynamic functions for beryl

In pegmatites, bertrandite forms in the late stages, commonly forming as a hydrothermal alteration product of beryl or other beryllium phases often with euclase, muscovite, or bavenite coprecipitating as the sink for aluminum released in the alteration process Euclase is relatively rare and is generally found in lowertemperature latestage
