      <abstract xml:lang="ru">
        <p>Приведены результаты минералого-технологических и геохимических исследований черносланцевых пород. Черные сланцы рассматриваются в качестве нового перспективного и нетрадиционного источника благородно- и редкометалльного сырья. Показано, что коллоидно-солевая фракция (нанофракция) с размером частиц менее 1000 нм составляет до 3 % по массе проб черных сланцев и извлекается водой при специально подобранных условиях. Использование воды вместо химически активных реагентов гарантирует отсутствие растворения минеральной матрицы и наиболее полно отражает коллоидно-солевую составляющую проб. Полученные результаты предопределяют направления создания новых методов и технологий обогащения углеродистого сырья при комплексном освоении твердых полезных ископаемых в горно-промышленных и нефтепромысловых районах России.</p>

        <p>The results of mineralogical, geochemical and technological research of black shale rocks are given. It is proved that black shales are now regarded as a new promising and innovative source of precious and rare-metal raw materials. It is pointed out that 3 wt. % of black shales samples is colloid-salt fraction (nanofraction) with a particle size less than 1000 nm and it can be extracted with water under specially chosen conditions. The use of water instead of chemically active reagents guarantees the absence of dissolved mineral matrix and clearly shows the colloidal salt component in samples. The results determine the direction of creating some new methods and technologies of carbonaceous feed dressing for integrated development of solid minerals in the mining and oil producing regions of Russia.</p>
