Disclosed is a multi-stage sedimentation rake-free thickening device. The device includes a central tank. A diversion sedimentation zone is arranged on the outside of the center tank. The diversion sedimentation zone includes an annular diversion sedimentation screen and a concentrated magnetic shower. The annular diversion sedimentation screen includes an annular groove spirally arranged around a central groove body. The annular groove is sequentially arranged with second spoiler baffles along the length direction. The lower bottom plate of the annular groove is also provided with second underflow discharge port. Multiple second inclined plate diversion discharge pipe is arranged under the corresponding second underflow discharge ports. The outlets of all the second inclined plate guide discharge pipes are collected to the second underflow discharge pipe, and the settled water is discharged from the second overflow discharge pipe arranged at the end of the annular groove.

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.

A golf bunker cleaning device includes a base having an open top end and an open bottom end defining an interior open space therebetween and the base configured to be buried below a ground surface of a golf bunker without filling in the interior open space. An extension collar is configured to be removably secured over the open top end of the base to increase a height of the interior open space to above the ground surface of the golf bunker, and a lid is configured to be removably secured over either the top end of the base or over the extension collar to enclose the interior open space. The extension collar comprises a plurality of collar latches each extending to a respective free end, and the base comprises a plurality of base locking apertures configured to releasable engage the respective free end of the plurality of collar latches.

A mineral recovery system for use in a mining operation is described. The mineral recovery system includes a mining operations model generated based on inputs of sensed conditions, wherein the mining operations model incorporates a thickener sub-model and a material sub-model. The mineral recovery system includes a thickener controller to issue commands based on the mining operations model. The mineral recovery system includes a thickener having a process water. The thickener also includes an underflow output provided with an underflow controller to adjust outflow of thickened slurry from the thickener based on issued commands. The thickener further includes an overflow output to dispense clarified water from the thickener.
