Considered structurally-mechanical, acoustic properties enclosing rocks to justify recommendations on the disintegration of sand placer deposits of gold and rare metals. It is noted that the deepening of theoretical and experimental researches in the area of influence of physical and mechanical processes, initiate cavitation effects, will solve the important problem of the disintegration of the gold-bearing sands. Keywords: disintegration, acoustic properties, wave impedance, shear modulus, cavitation.
