The article discusses the results of studying the material composition and the
development of technology for processing gold-bearing sulfide ore samples. The material
composition of the ore samples was studied by spectral, chemical, assay and rational analysis of
gold and silver. Based on a study of the material composition of the ore samples, the following

Maqolada oltin sulfidli ma'danli namunalarni qayta ishlash texnologiyasi va moddiy tarkibini
o'rganish natijalari bayon etilgan. Javhar namunalarining moddiy tarkiblari oltin va kumushdan
spektral, kimyoviy, tahlil va oqilona tahlillar orqali o'rganiladi. Rudalar namunalarining moddiy
tarkibini o'rganish asosida quyidagi xulosalar berildi: oltin va kumush sanoatning eng qimmatli
qismlari. Graviyofloraf kontsentrati kubiklaridan sulfat kislota bilan ishlashni qo'llash
jarayonning texnologik samaradorligini oshirish imkonini beradi. Gravio-flotatsion konsentrat

В статье рассматриваются результаты изучения вещественного состава и
разработка технологии переработки золотосодержащих сульфидных проб руды.
Вещественный состав проб руды изучен спектральным, химическим, пробирным и
рациональным анализами на золото и серебро. На основании изучения вещественного
состава проб руды сделаны следующие выводы: промышленно-ценными компонентами
пробы являются золото и серебро. Показано, что применение сернокислотной обработки
огарка гравио-флотоконцентрата может улучшить технологические показатели
процесса. В результате смеси гравио-флотоконцентрата после сернокислотной
обработки сушки, измельчении до крупности 95% кл. -0,074+0 мм подвергали
сорбционному цианированию. В исходном кеке содержание золота -77,83 у. е. и серебра -16,3 у. е., концентрация цианистого натрия 0,15%, соотношение ж:т=2:1; смола АМ-2Б-5% от объема пульпы, продолжительность цианирования 36 ч. Содержание в хвостах
цианирования золота - 6,5 у. е., и серебра - 4,8 у. е. Извлечение благородных металлов в
растворе и на смолу составило 91,65 и 70,55%, соответственно. Сквозное извлечение
золота -87,63% и серебра - 55,6% из руды.
