1. An apparatus, comprising:
a placer-gold processing system, including:
an upstream section being configured to receive gravel and flowing water thereby forming flowing slurry having placer gold;a gold-concentrator assembly being configured to be in fluid communication with the upstream section;a gold-detection assembly being configured to be in fluid communication with the gold-concentrator assembly; anda magnetite-separator assembly being configured to be in fluid communication with the gold-concentrator assembly; and wherein the placer-gold processing system further includes:
a self-flushing riffle region, including:
a riffle body defining riffle grooves that are each spaced apart from each other along a length of the riffle body; andthe riffle grooves being configured to receive the flowing slurry having the placer gold, and the placer gold falls, via gravity, into the riffle grooves as the placer gold travels along the riffle body, and any of the placer gold, which is not received by the riffle grooves, exits the gold-concentrator assembly via a waste output region; andan output of the riffle grooves are directed to the gold-detection assembly; and wherein the gold-detection assembly includes:
a gold-indicator section including any one of sandpaper, coarse material, textured material, porous material, soft rubber and a sticky material being positioned in the gold-detection assembly in such a way that the gold-indicator section, in use, temporarily retards, at least in part, motion of the placer gold being conveyed by the flowing slurry as the flowing slurry moves past the gold-indicator section, and the placer gold, which was temporarily retarded from motion by the gold-indicator section, is visually displayed to a user; andwhereby the gold-detection assembly assists the user to locate the desirable gravel that provides the desirable amount of placer gold by having the user visually monitor the gold-detection assembly for a temporarily retarded amount of the placer gold, and once the amount of placer gold, which is temporarily retarded and visually displayed to the user, is desirable, the user can then focus on the site which provides this condition while avoiding continued prospecting of unproductive sites and thereby avoid wasting time, and the gold-detection assembly provides an opportunity, for the user, to view whether there is any placer gold in each shovel of gravel feed into the upstream section; and wherein the gold-detection assembly includes:
an open container assembly including:
an input section configured to fluidly receive the flowing slurry carrying the placer gold; andan output section in fluid communication with and positioned downstream from the input section, and the output section configured to output the flowing slurry carrying the placer gold received from the input section; andthe gold-indicator section is fixedly positioned downstream from the input section and upstream from the output section; andthe gold-indicator section is configured to contact, at least in part, the placer gold conveyed by the flowing slurry carrying the placer gold arriving from the input section; andthe gold-indicator section is also configured to retard, at least in part, the motion of the placer gold relative to the flowing slurry as the flowing slurry moves toward the output section; andthe gold-indicator section is also configured to temporarily hold and retard, at least in part, the motion of the placer gold conveyed by the flowing slurry received, at least in part, from the input section in such a way that some amount of the placer gold is temporarily held by the gold-indicator section as the flowing slurry moves past the gold-indicator section; andthe gold-indicator section is also configured to visually display, at least in part, the placer gold that was retarded from motion relative to the flowing slurry as the flowing slurry moves toward the output section; and wherein the magnetite-separator assembly includes:
a disk configured to rotate; andpaddles that extend radially from the disk; andthe disk and the paddles configured to be driven, operated and rotated by an input of the flowing slurry onto the magnetite-separator assembly; anda magnetite-attraction area including a magnet mounted to the disk; andthe magnet configured to attract and retain magnetite that is directed from the gold-detection assembly toward the disk in such a way that the placer gold and fine sand deflects from the disk to a sluice assembly to an output area of the magnetite-separator assembly;a nozzle oriented toward the disk and the paddles; andthe nozzle configured to direct a stream of water, via a water spray, with enough strength that the magnetite that is held by the magnet is knocked off the disk and travels into a magnetite catcher; andas the disk is made to rotate in the flowing slurry, the magnet, in use, removes the magnetite from the flowing slurry, and the nozzle, in use, removes the magnetite from the disk and also urges rotation of the disk. |
