Column Flotation Testing Better Improved Recovery

Fluorite rougher column plug flow retention times based on slurry feed rate and collection zone volume (column volume between feed injection port and air sparger) were approximately 5 min compared with conventional flotation retention times of 15 min. Flow to subsequent processing stages was maintained as necessary to match discharge from the fluorite rougher column....

The desired hydrophobic mineral will then attach to the air bubbles and float to the top of the flotation cell, where it will be skimmed off as a mineralladen froth. The remaining unfloated mineral slurry will be discharged as tailings. Most flotation circuits include an initial stage of rougher flotation, followed by a scavenger stage of ......

The flotation time determined in laboratory flotation cells is a basis for design and construction of plant operating units. For coal, these times are between 5 and 10 minutes, these are known to be longer for ores and industrial minerals and for rougher flotation of difficult minerals can even be up to one hour....

The target recovery and mass pull may be achieved using only one rougher column flotation stage, and thus no additional flotation stages are required ( cleaner or scavenger stages). Once the shakeout/development pilot work is completed, bulk concentrate production will begin with the plant operating for approximately 10 days to produce approximately 1,000 kg of flotation concentrate....
