Chemical enrichment of substandard beryllium concentrates

Abstract

Global trends in the use of beryllium in the creation of high-tech products dictate the need to create beryllium production in Russia. The prerequisites for this are the availability of a raw material base and competencies in the field of technology for the production of beryllium metal and products based on it. The most promising are the ores of the Malyshevsky deposit (JSC "Mariinsky Mine"), with an ore content of 0.12–0.14 % according to BeO, the approved reserves of which will last for 30–50 years of uninterrupted mining. As a result of exploratory research on the chemical enrichment of 5 % BeO flotation concentrate, a basic technological scheme was developed, and a high-grade concentrate with a BeO content of more than 10 % was obtained. Solving the problem of obtaining high-quality concentrate will solve a complex of problems in the raw material — technology — production of beryllium metal and products based on it.
