Abstract

Procedimiento y dispositivo para la producción de burbujas aptas para asegurar el tratamiento de una suspensión por flotación, el procedimiento caracterizado porque en una conducción donde se hace circular la suspensión enriquecida de gas disuelto hasta una cubo de flotación, se corta bruscamente el flujo o deslizamiento según una frecuencia predeterminada por medio de un órgano de obturación de cierre brusco que produce a su salida en la conducción una onda depresiva periódica tal que provoca burbujas de cavitación en el flujo o deslizamiento a esta altura, propagándose esta onda depresiva en la conducción hasta la cuba de flotación donde se refleja en onda de presión que produce el colapso de las burbujas de cavitación con formación de micro-burbujas susceptibles de engancharse un las partículas a hacer flotar, siendo las condiciones en la conducción tales que las micro-burbujas se encuentren en un medio sobresaturado con respecto a las condiciones locales de presión y tengan tendencia aaumentar durante su trayectoria hasta la cuba de flotación.
