FIELD: mining. ^ SUBSTANCE: flotation method includes fresh pulp supply in a vibration flotation machine mixing chamber, and pulp aeration, executed with a bubbler help. In the vibration chamber gas-liquid mixture treated with turbulence, with low frequency vibrations amplitudes, selected in a way that low density particles do not brake away from air bubbles due to inertia force, but particles with a bigger density do brake away from air bubbles due to inertia force, and frequency, calculated via well-known formula for gas-liquid mixture resonance oscillation frequency calculation, where f - the gas-liquid mixture resonance oscillation frequency in the vibration chamber, Hz; i=1,2Çk - harmonic oscillations order number, a - the gas-liquid mixture acoustic speed in the vibration chamber, m/s; H - gas-liquid mixture height level in the vibration chamber, m. Method to be realised on the vibration flotation machine, which includes the pulp mixing chamber with installed a self-priming mixer inside of it, a foam product reloading chamber, a chamber product withdrawal outlet, equipped with the vibration chamber with installed a reflection wall and the bubbler inside and also equipped with a circulation contour and a circulation intensity control valve. ^ EFFECT: flotation efficiency increase and machine power consumption decrease. ^ 2 cl, 1 dwg, 1 ex |
