“Mongolrostsvetmet” LLC exploit its fluorspar ore from Bor-Undur underground mine and Khukh Del /Tuv ungent and Zuun unegt/ open pit mint. The fluorspar ore from these mines are processed in the Bor-Undur ore dressing plant (ODP) and produce Fluorspar acid concentrate (FF-97, FF-95) and metallurgical concentrate (FK-75) as final products. The “Bor-Undur” concentration plant is considered to be the largest Fluorspar concentrate processing plant in Mongolia.
