1 Introduction

Flotation implies that particles are carried by bubbles and this can affect gas hold-up without changing bubble size Garibay et al [16] tested the impact of increasing solids content (%solids) in a flotation column where gas hold-up tends to increase up the column reflecting the increase in bubble size (volume) as static head pressure decreases
