Column Flotation - SGS

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 rectangular. The fabrication cost for rectangular columns is significantly higher than for circular columns, as approximately twice the mass of steel is required; however, there is no evidence that rectangular columns
