20140339140 | Gravity Separator - An apparatus, method, and system are provided for separating material. In some embodiments the separator may include a deck. The deck may accept the material to be separated at a feed end and may provide separated output material at a discharge end. The flow of the material along the deck from the feed end to the discharge end may define a feed direction. The deck may be subject to a vibration or conveyance aligned with the feed direction. The deck may include riffles or corrugations. The riffles may be oriented at an angle relative to a direction of the vibration or conveyance, or at an angle relative to the feed direction. The deck may be subjected to an end-to-end elevation or slope. The end-to-end slope may be positive/downhill, negative/uphill, or zero. | 11-20-2014 |

20090139910 | Separation of metals from sand - The present invention provides a method and an apparatus for removing heavy metals such as gold from sand. A mixture of sand and metals is placed in a hollow tube which has an open end, an opposite closed end at a relatively lower position, an exterior, and an interior formed into spiral grooves. The grooves are arranged in a helical fashion so that metal caught in the grooves is carried toward the open end of the tube as the tube is rotated. Water is supplied to the tube to mix with the sand and metal, so that rotation of the tube causes relatively heavy metal to be washed from the sand and water mixture into the grooves. The mechanism can be transported to a location where heavy metals naturally occur in sand or other materials. | 06-04-2009 |

20130008835 | SYSTEM AND METHOD FOR SEPARATION OF MATERIALS OF DIFFERENT SPECIFIC GRAVITIES - A system, method and apparatus for separating materials of different specific gravities including a material flow-path surface having a trap structure with an oscillator coupled thereto to cause oscillation thereof while the surface is immersed in a standing fluid. | 01-10-2013 |
20140202934 | SYSTEM AND METHOD FOR SEPARATION OF MATERIALS OF DIFFERENT SPECIFIC GRAVITIES - A system, method and apparatus for separating materials of different specific gravities including a material flow-path surface having a trap structure with an oscillator coupled thereto to cause oscillation thereof while the surface is immersed in a standing fluid. | 07-24-2014 |

20130032513 | Multi-Deck Air Jigging Machine - An air jigging machine for dry processing of raw materials, an air supply conduit for supplying working air to an air funnel, and having a pulsing valve. At least two jigging-material carriers for receiving material from a material-feeding mechanism are configured to consecutively receive therethrough working air from the air funnel and to separate the material into heavy and light material layers. The jigging-material carriers are disposed one above the other and are spaced apart. A wall encloses this intermediate space. At least one bypass airline branches off from the air supply conduit downstream of the pulsing valve, bypasses the lower jigging-material carrier, and communicates with the intermediate space for supplying an additional working airflow thereto. Respective discharge devices are provided for the jigging-material carriers for the material layered thereon during a jigging process. | 02-07-2013 |
20150306632 | Empty seed shells removing apparatus - The empty seed shell removing apparatus has a main body including an interior, an interior floor portion, a top portion including air intake openings, a front portion having a front opening, and a front portion having an air exhaust opening. A fan assembly attached within the interior of the main body and including a fan member adapted to create an air stream from the air intake openings, around and through the interior, and out through the air exhaust opening; and a shell container sized and shaped to removably slide and fit within the front opening. The shell container includes a bin section adapted to hold the mixture of full seed shells and empty seed shells, wherein when the shell container is full of the mixture of full seed shells and empty seed shells and placed within the main body the fan member is activated creating the air stream from the air intake openings, around and through the interior, and out through the air exhaust opening, such that the air stream circulates through the mixture of full seed shells and empty seed shells causing the empty seed shells to fly out of the bin section while leaving the full seed shells therein, and wherein the empty seed shells end up upon the interior floor portion ready for removal once the fan member is deactivated. | 10-29-2015 |

20110174699 | Metal detecting gold pan - A metal detecting gold pan for speeding the location, identification and recovery of ferrous or non ferrous metals from parent materials. Metal detecting electronics and sensors in proximity to, connected by cord to, and imbedded in the body of the pan sense and identify metals inside or outside the pan. The metal detecting gold pan is used in the traditional manner, using either wet or dry methods for materials separation. Metals consolidating in the interior of the pan are electronically sensed and identified. Metal bearing parent material external to the pan may be located by using a sensor in the bottom of the pan. Time and effort to reduce overburden and identify materials is greatly reduced during the panning process. | 07-21-2011 |
