Abstract

Disclosed herein is a method comprising discharging a slurry from a vessel to a conduit; where the slurry comprises a liquid and a composition comprising at least two materials having different densities-a first material having a higher density and a second material having a lower density than that of the first material; creating a surge in velocity in slurry flow as it is transported through the conduit; separating the first material from the second material; where the first material is disposed on an inner surface of the conduit and where the second material flows through the conduit to a container; and removing the first material from the inner surface of the conduit.

Claims5

Dependent claims

A device comprising:

a vessel having an inlet port and an outlet port;
where the vessel is provided with an agitator that is operative to agitate a content of the vessel;
at least one of a compressor and a pump that is in fluid communication with the vessel through a valve;
where the compressor is in fluid communication with the inlet port;
where the compressor lies upstream of the vessel;
where the pump is in fluid communication with the outlet port;
where either the pump, the compressor and the valve, or the pump and the valve are operative to produce a surge in a flow of a slurry discharged from the vessel;
and
a conduit in fluid communication with the outlet port;
where the conduit contacts the pump outlet and has a steady incline of 3 degrees to 45 degrees from the pump outlet with respect to a horizontal;
where the surge in the flow of the slurry is effective to separate particles of different densities during their flow inside the conduit;
where a first material is disposed on an inner surface of the conduit and where a second material flows through and exits the conduit;
and wherein the first material has a higher density than the second material.
