Abstract

Perfeccionamientos en máquinas de flotación de aire disperso, en la cual se utilizan efectos hidráulicos para dispensar las burbujas de gas en todo el líquido contenido, caracterizados porque incluye cada máquina una cámara y una pluralidad de celdas de flotación, sin desviadores o elementos mecánicos para la distribución de gas, montadas unas en posición adyacente a otras, en una serie horizontal dentro de la cámara, y en la cual cada celda contiene un cuerpo de líquido con una superficie libre, un dispositivo conectado a la cámara para introducir líquido que deberá ser procesado en su interior, dispositivo para pasar el líquido al procesamiento de una celda a la otra dentro de la cámara, dispositivo para desalojar la espuma de la superficie libre del líquido en cada una de las celdas de flotación, un dispositivo expulsor de fluido montado fijamente en cada una de las celdas de flotación en una posición apta para expulsar un fluido bifásico mixto al interior del líquido contenidoen la celda de flotación asociada.
