Abstract

Se divulga una celda de flotacion (1) para tratar particulas suspendidas en suspension y para separar la suspension en un reflujo inferior (400) y un desbordamiento (500). La celda de flotacion comprende un tanque de flotacion (10) con un centro (11), un perimetro (12), un fondo nivelado sustancialmente horizontal (13) y una pared lateral (14); una artesa (2) y un pico de artesa (21) que rodea el perimetro (12) del tanque (11); y una estructura del fondo (7) dispuesta en el fondo (13), y tiene una forma que permite que las particulas suspendidas en la suspension se mezclen en una zona de mezcla (A) sobre la estructura del fondo, y se asienten en una zona de asentamiento (B ) rodeando la estructura de fondo. El tanque de flotacion comprende ademas tubos de explosion (4) para introducir la alimentacion de flujo (100) en el tanque. Ademas, se divulga una linea de flotacion y el uso de la linea de flotacion.A flotation cell (1) is disclosed for treating suspended particles in suspension and for separating the suspension into a lower reflux (400) and an overflow (500). The flotation cell comprises a flotation tank (10) with a center (11), a perimeter (12), a substantially horizontal level bottom (13) and a side wall (14); a tundish (2) and a tundish spout (21) surrounding the perimeter (12) of the tank (11); and a bottom structure (7) arranged on the bottom (13), and has a shape that allows the particles suspended in the suspension to mix in a mixing zone (A) on the bottom structure, and settle in a settlement zone (B) surrounding the bottom structure. The flotation tank further comprises blast tubes (4) for introducing the flow feed (100) into the tank. In addition, a waterline and the use of the waterline are disclosed.
