Осуществлен энергодисперсионный микроанализ образцов пород. В пробах присутствуют микроэлементы широкого спектра благородных (в том числе золота, серебра, платины), редкоземельных и других элементов. Установлено, что пески исследуемой золотоносной россыпи являются достаточно сложным объектом для дезинтеграции. Экспериментально-аналитическим путем определены акустические характеристики исследуемых песков в исходном состоянии и при водонасыщении, которые свидетельствуют о значительном превышении доли максимальных значений модуля сдвига. Для решения вопроса микродезинтеграции, с целью извлечения мелкого и тонкого золота более экологически и технологически эффективными средствами, предложено использовать системы, в основе которых лежат процессы кавитационно-акустического воздействия на минеральную составляющую гидросмеси.</p></abstract><trans-abstract xml:lang="en"><p>The paper considers research findings on sands from the high-clay alluvial compound complex deposit of the Fadeevsky ore-placer site characterized by high sand strength characteristics and by an elevated content of small fractions of valuable components. The paper describes an energy-dispersive microanalysis of rock samples. The samples contain trace elements of a wide range of noble (including gold, silver, and platinum), rare-earth and other elements. It was established that sands from the gold-bearing placer under study constituted a rather complex object for disintegration. Acoustic characteristics of sands under study in their original state and after water saturation were determined experimentally and analytically. They indicate a significant exceedance of the proportion of shear modulus maximum values. In order to solve the microdisintegration problem for the purpose of extracting small and fine gold by more environmentally and technologically efficient means, the paper proposes to use systems based on processes of cavitation-acoustic influence on the mineral component of the slurry.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дезинтеграция</kwd><kwd>водонасыщение</kwd><kwd>волновое сопротивление</kwd><kwd>скорость продольных и поперечных волн ультразвука</kwd></kwd-group><kwd-group xml:lang="en"><kwd>disintegration</kwd><kwd>water saturation</kwd><kwd>wave resistance</kwd><kwd>velocity of longitudinal and transverse ultrasound waves</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Архипов Г.И.
