Abstract:
Provided is a gravity separation device wherein occurrences of shelving, flashing, and the like inside the device can be suppressed, variations in the flow rate of underflow obtained by gravity separation can be minimized and underflow can be stably extracted. This gravity separation device, which separates overflow and underflow using differences in specific gravity from mixed material, is provided with a separation section that has a supply pipe for supplying a slurry of the mixed material at the top and separates that slurry into overflow and underflow, and a deposition section that is positioned below the separation section and wherein the underflow that has been separated by precipitation is deposited. An extraction pipe for extracting the underflow is connected to the deposition section, and a valve for extracting the underflow and a metering pump for quantitatively extracting the underflow are provided in the extraction pipe.

Claim (Index 3):
The gravity separation device according to  claim 1 , wherein the slurry of the mixed material is ore slurry of nickel oxide ore.
