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.

First claim

What is claimed is:

1. 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.

2. The device of claim 1 , where the agitator is a stirrer that is operative to subject the content of the vessel to rotary motion.

3. The device of claim 1 , where the pump is a peristaltic pump, a centrifugal pump, a gear pump, a screw pump, a progressing cavity pump, a Roots-type pump, a plunger pump, a triplex-style plunger pump, a compressed-air-powered double-diaphragm pump, a rope pump, or a flexible impeller pump.

4. The device of claim 1 , where the pump is a peristaltic pump.

5. The device of claim 1 , where the valve is a ball valve, a gate valve or a sluice valve.
