Column Flotation
A schematic of a flotation column is shown in Figure 1. Industrial flotation columns are 6-14 m in height (from the bottom discharge to the top lip), and range in diameter from 0.5 to 5 m. Recent large scale applications have typically been 4 to 4.5 m diameter and approximately 12 m tall. [There are many installations of columns that are ...

Column flotation simulation and control: An overview
Bubble surface area flux.The collection of mineral particles by bubbles greatly depends on the amount of bubble surface available. Therefore, a more adequate way of tracking the influence of gas to the flotation process is to use the amount of bubble surface per unit time and unit of column cross sectional area instead of the gas hold-up. This …
