      <abstract xml:lang="ru">
        <p>В статье приведены результаты исследования возможности оценивания упорности золотосодержащих руд с помощью данных термического анализа. В качестве объектов исследования использовались флотационные концентраты, полученные при обогащении дважды упорных сульфидных золотосодержащих руд. Данный тип руд осложнен тонкой вкрапленностью золота в сульфидные минералы, присутствием сорбционно активного рассеянного углеродистого вещества, находящегося в тесной ассоциации с сульфидами. Приведены результаты термогравиметрических и масс-спектрометрических исследований упорных золотосодержащих руд. Полученные фрагменты для керогена CH (m/z = 15), C2H (m/z = 29) и C3H (m/z = 43) свидетельствуют о наличии в исследуемых образцах различных типов углеродистого вещества. Обосновано, что степень сорбционной активности углеродистого вещества зависит от присутствия в руде керогенов и битуменов. Высокая сорбционная активность рассеянного углистого вещества существенно влияет на технологию переработки руд и концентратов как флотационными, так и пиро- и гидрометаллургическими методами. Термогравиметрический и масс-спектроскопический анализы могут применяться для определения степени прегроббинга упорных золотосодержащих руд. Полученные результаты предопределяют направления создания новых методов и технологий в области обезуглероживания упорных золотосодержащих руд при комплексном освоении твердых полезных ископаемых в горнопромышленных районах России.</p>

        <p>The article presents the results of a study on the possibility to assess refractory gold-bearing ores using thermal analysis data. It studies the flotation concentrates obtained during the enrichment of double refractory sulfide gold-bearing ores. This type of ore is complicated by the fine impregnation of gold in sulphide minerals and the presence of sorption-active scattered carbonaceous matter, which is in close association with sulphides. The results of thermogravimetric and mass spectrometric studies of refractory gold-bearing ores are presented. The obtained fragments for kerogen CH (m/z = 15), C2H (m/z = 29) and C3H (m/z = 43) indicate the presence of various types of carbonaceous matter in the studied samples. It is justified that the degree of sorption activity of carbonaceous matter depends on the presence of kerogen and bitumen in the ore. High sorption activity of scattered carbonaceous material significantly affects the processing technology of ores and concentrates, both flotation and pyro- and hydrometallurgical methods. Thermogravimetric and mass spectroscopic analyzes can be used to determine the degree of preg-robbing of refractory gold-bearing ores. The obtained results predetermine the direction of creating new methods and technologies in the field of decarburization of refractory gold-bearing ores in the integrated development of solid minerals in the mining regions of Russia.</p>
