Abstract
A unit, which generates sonic energy for use in the leaching or extraction of minerals from ore, is mounted in a tank which contains the leaching solution and the ore. The unit has a housing in which a solid bar is supported by means of a rod which fits into a bored out bottom portion of the bar which is along the longitudinal axis thereof, as well as a plurality of resilient lateral spoke members which protrude inwardly from the housing and abut against the bar. An orbiting mass oscillator is mounted on the bar on the top end thereof and is rotatably driven to effect resonant standing wave vibration of the bar in a quadrature nutating vibration mode. The oscillator is positioned above the leaching solution and the ore so that it is free therefrom, the rod member used to support the bar and the resilient lateral support members being abutted against the bar at nodes of the standing wave vibration pattern established in the bar to minimize energy losses into the housing.
