      <abstract xml:lang="ru">
        <p>В работе представлен анализ исследований обогатимости сульфидных и окисленных руд месторождений Якутии. Руда месторождения представляет собой смесь первичных, смешанных и окисленных руд. Основным полезным компонентом руды месторождения является золото при содержании в исследованных технологических пробах от 1,5 до 2,8 г/т, содержание серебра низкое – 5-17 г/т. Рудные минералы представлены сульфидами, среди которых преобладает пирит. Общее содержание сульфидов не превышает 3-5 %. Отмечено наличие в руде свободного и связанного золота крупностью от долей мкм до 1,5 мм. Золото представлено самородной формой в срастании с сульфидами, а также образует самостоятельные включения. Руды относятся к категории легко цианируемых. Установлено, что содержание амальгамируемого золота составляет 10-49, доля цианируемого золота колеблется в пределах 66,67-91, на долю упорного золота приходится 9,0-33,33 %, что в абсолютном значении составляет 0,24-0,8 г/т. Извлечение золота в гравитационный концентрат варьируется в зависимости от содержания золота в руде и выхода концентрата и составляет для руд с содержанием золота 1,5-2,8 г/т от 40 до 60 %. Прямым цианированием всех исследованных проб руды установлена возможность извлечения золота в раствор до 86,7-92,9 %, содержание золота в кеках цианирования составляет 0,2-0,3 г/т. Исследования гравитационного концентрата методом интенсивного цианирования показали, что при исходном содержании золота ~500 г/т в раствор извлекается до 98,9 %. Содержание золота в кеках интенсивного цианирования составит 6-15 г/т. Выполненный авторами статьи комплекс исследований в различных институтах показал, что переработку руды месторождения целесообразно осуществлять по технологии цианирования с предварительным гравитационным выделением золота.</p>

      <abstract xml:lang="en">
        <p>The paper presents the analysis of studies of the enrichment of sulfide and oxidized ores in Yakutia deposits. The ore of the deposit is a mixture of primary, mixed and oxidized ores. The main useful component of the studied ore samples is gold with a content of 1.5 to 2.8 g/t, the silver content is low – 5-17 g/t. Ore minerals are represented by sulfides, among which pyrite predominates. The total sulfide content does not exceed 3-5 %. The presence in the ore of free and associated gold with a grain size from fractions of a micron to 1.5 mm. Gold is represented by nuggets in intergrowth with sulfides and also forms independent inclusions. Ores are classified as easily cyanidable. It was found that the content of amalgamable gold is 10-49, the share of cyanidable gold ranges from 66.67-91, the share of refractory gold is 9.0-33.33 %, which in absolute amount equals to 0.24-0.8 g/t. The extraction of gold in gravitation concentrate varies depending on the gold content in the ore and the yield of concentrate and for ores with a gold content of 1.5-2.8 g/t from 40 to 60 %. The direct cyanidation of all studied ore samples established the possibility of extracting gold into solution up to 86.7-92.9 %, the gold content in cyanidation cakes is 0.2-0.3 g/t. Investigations of the gravitation concentrate by the method of intensive cyanidation showed that with an initial gold content of ~ 500 g/t, up to 98.9 % is extracted into the solution. The gold content in intensive cyanide cakes will be 6-15 g/t. A set of studies carried out by the authors of the article at various institutes showed that it is advisable to process ore from the deposit using cyanidation technology with preliminary gravitational extraction of gold.</p>
