Operation of a pilot heavy medium separation plant allows flexibility of operation not normally possible in an operating plant. Much useful data can be obtained, although some limitations apply._x000D_
Projects carried out at AMDEL have included HMC separations at 1.5 to 3.6 specific gravity, comparative operation of HMC and DWP separators and the use of fine feed and product screens._x000D_
Investigations of this type have provided a considerable amount of information on HMS plant performance and characteristics under a wide range of operating conditions.
