Establishment of mutually beneficial cooperation between “Erdenet Mining Corporation” and scientific and research ent. “Bourevestnik” has been set early 1980s. In that period “Bourevestnik” produced and delivered two units for automatic complexes of analytical control built around X-ray analyzer type AR to “Erdenet”. Works have been carried together with “Mechanobr” ent.

In December 2014 within the framework of signed agreement “Bourevestnik” performed start-up works for analytical complex built around X-ray AR-31-M device. Analyzer AR-31-M is a key instrument of ore enriching technology at “Erdenet Mining Corporation” intended for express constant fluorescent evaluation of fifteen technological products within processing Cu, Mo ore. New equipment built around a AR-31-M slurry analyzer enables the achievement of pre-required technological process characteristics of ore dressing at a level set by the technology.
