New Eriez StackCell improves flotation cost and performance
Several years ago, a 1.2-metre diameter unit was tested in gold sulphide flotation in South America. In the comparison, the StackCell was run side by side with a conventional mechanical tank cell and was able to achieve a comparable degree of metallurgical separation (as measured by grade and recovery) in about one-sixth of the …

Flotation Time Scale-up Factors – Laboratory to Plant
This project is a "Copper flotation" project with some Moly (<200ppm). The chosen scale-up was 2.5 while The Book calls for on copper 2.1X. Without have access to the complete metallurgical testwork data and results I'd say 2.5X was the extra chosen to factor in Moly recovery which The Book calls for 2.6X.
