New Data on the Metal Content of Sakhalin Coals

The levels of concentrations of valuable impurity elements in coals from a number of Sakhalin deposits were studied. It was established that all the studied deposits are potentially commercial metal-bearing in terms of Sc, REEs, Cs, Rb, and Sr. A wide range of valuable metals with minimal commercial concentrations—Ge, Sc, Mo, Y, W, Cs, Rb, Sr, and Sb—was identified in the Novikovskoye germanium–coal deposit (sections Vostochnyi 1 and Rezervnyi). An estimate of the predicted resources of valuable metals in this deposit was made, and the large resource potential of valuable metals in the coals of Sakhalin was concluded.
