Mini flotation pilot plant testing is typically performed for batches of ore concerning either roughing or cleaning. The aim of conducting these tests is to confirm the ore geometallurgical classes (generally lithological types) and flotation conditions based on the relationship between quantitative mineralogical results and beneficiation tests.

The plant ran with difficulty; lots of big shutdown problems and the process fume destroyed the local environment; all of this would have been discovered and remedied if they had piloted the project, but pilot was eliminated as a "money saving" step which cost more in capital replacement and operational down time than the pilot plant would have.
