The results of the study of high-Mg rocks from the Aganozero chromite deposit, located in the Republic of Karelia, are reported. It is a complex type of deposits. Other promising useful minerals, in addition to chromite ore mining, are Mg-rich ultramafics such as olivinite, dunite, serpentinite and pyroxenite. High-Mg dunite units are thick, and their MgO concentration varies 36.97 from 46.77%. Aganozero dunite is a good raw material for the production of refractory materials, e.g. refractory bricks, steel furnace...

The present study was conducted to develop a method for utilization of serpentinized ultramafic rocks as mining waste using nature conservation technologies. In this method, the original raw material is thermally activated to obtain an active metastable phase. The goal of the study is to produce a granulated Mg-silicate reagent used to remove heavy metal compounds from solutions. Pentinsuo antigorite, Ozerki soapstone deposit in the Kostomuksha area, Karelia, Russia, and serpophyte from the Pilguj?rvi massif, Pech...
