Abstract

The paper describes the development of automatic X-ray fluorescent unit (XFU) intended for the express analysis of pulp slurries, as well as its software, methodical–mathematical and metrological support. It is emphasized that this XFU modification is difficult to implement but is best suitable for mineral processing plants, first of all, for operational control of flotation processes. In accordance with the concept of an automated analytical control accepted by RIVS, the designed automated analytical control system (AACS) is composed of XFU joined with an automated pulp sampling system (APSS) The authors review in brief the functions of the full-scale AACS and its constituents — XFU and APSS. The emphasis is made on the problems and features of XFU with the particular attention given to its analytical and instrumentation characteristics. The designed unit is compared with the best Russian and foreign analogues. The results of the analysis of powder and pulp samples of ore and ore dressing products are presented. It is shown that prime calibration of XFU is possible using model pulps — boric acid-based pellets. Finally, the authors conclude that the designed XFU meets the demands imposed on the express analytical control of ore and ore dressing precuts, and is usable as a prototype for various modifications.
