Abstract
Se describe una unidad de flotacion (10) por espuma para el tratamiento de particulas de mena mineral suspendidas en suspension (1). La unidad de flotacion por espuma comprende un tanque (11), un suministro de gas para introducir gas de flotacion (2) dentro de la suspension para formar espuma (3), y un primer canal rebosadero (21) de recoleccion de espuma que comprende un primer borde (121a) de desbordamiento de espuma que da la cara hacia el centro (111) del tanque (11). La unidad de flotacion por espuma tiene un area de pulpa (A) de al menos 15 m2, medida en un area de mezclado (140). La unidad de flotacion por espuma ademas comprende un segundo canal rebosadero (22) de recoleccion de espuma dentro de un primer borde de rebosamiento (122a) de espuma orientado al perimetro (110) del tanque de flotacion (11), y un bloqueador de espuma (31) dispuesto entre el primer borde (121 a) de desbordamiento de espuma y el segundo borde (122a) de desbordamiento de espuma. Tambien se describen una linea de flotacion por espuma, su uso, y un metodo de flotacion por espuma.
