Flotation Cell Capacity vs Retention Time

An Example of flotation cell capacity and circuit retention time approximation: Estimate the volume of conditioners and flotation cells required to handle 9100 dry tons of ore per 24 hours at 30% pulp solids by weight, with an ore specific gravity of 3.1. Five minutes conditioning time and 15 minutes flotation time are desired.
