The authors present the objective conditions for creation of the proprietary automatic analytical control system ASAK-RIVS for mining and processing industry, including pulp assaying and analytical units. The composition and structure of the equipment is described. It is emphasized that design of the automatic X-ray fluorescence pulp analyzer as the backbone of the analytical unit is challenging. At the same time, this type analyzer is the highest-needed sensor of element composition for monitoring and control of process stages in ore beneficiation. The authors specify features of the proprietary multi-cell pulp analyzer and compare its detection limits with the performance of different X-ray fluorescence powder and pulp analyzers. It is highlighted in the article that the analytical unit based on the X-ray fluorescence pulp analyzer (RFA-RIVS) has been designed based on the unified programming, technical, mathematical and metrological decisions. Also, a validated approach to assessment of necessary and sufficient sensitivity of assaying and operating analytical control is presented. The advantages of ASAK-RIVS over the similar analytical systems are identified. Finally, it is concluded on conformity of the designed and patented RFA-RIVS and ASAK-RIVS systems with the modern requirements imposed on the same systems of instrumental express-analysis.
