PROBLEMS OF ANALYTICAL CONTROL IN PRODUCTION OF RARE AND PRECIOUS METALS

Abstract

The article focuses on one of the important issues in rare and precious metals industry development – analytical control. It reviews the current state, importance, problems and prospects for analytical control development as an integral part of the rare and precious metal production and product quality assurance. Modern analytical control methods are described, namely atomic spectral, mass spectral, X-ray fluorescent and combined ones as well as their rational applications. It is shown that scientific and technological progress is inextricably linked with a drastic increase in the nomenclature of materials based on rare and precious metals and higher requirements for their quality. This will require creating new and improving existing analytical control methods, their standardization and metrological support. This work should involve research organizations in theRussianAcademy of Sciences, universities, industry research centers with research laboratories that have survived in the country after theSoviet Union dissolution, as well as promote plant research activities. It is necessary to effectively use the achievements of advanced analytical laboratories abroad, participate in international comparative tests. At the same time, special attention is paid to unsolved problems – scientifically justified statement of requirements for new types of products based on rare and precious metals; development and metrological assessment of sampling methods; development of high-quality metrological support for analytical control of rare and precious metal production; improvement of analytical methods; standardization of analytical methods; accreditation of analytical laboratories; training of highly qualified analytical chemists.
