Abstract:
1. A portable and compact gold concentrator for separation of quantities of gold bearing sands and aggregate, providing three distinct process levels of separation and reduction of waste materials with retention of gold particles, said gold concentrator comprising: a first stacked tray defining a smooth flat inclined surface contained within a first end, second end and two lateral side portions having a first end defining a flood box with a water inlet wherein a smooth and controlled flow of water is introduced upon said smooth flat inclined surface, said smooth flat inclined surface locating an area for the deposit of gold bearing aggregate within said flow of water forming an aggregate slurry; a second stacked tray defining a smooth flat inclined surface upon which is secured a vortex mat defining a textured upper surface, said flat inclined surface contained within a first end, second end and two lateral side portions, said first end further providing a G force separator defining an axial trough with said first end having a smooth and rounded axial surface and incorporating a vertical gate descending from said second end of said first stacked tray within said axial trough, wherein said aggregate slurry is separated by three physical processes into various minerals to collect any gold content within said aggregate slurry, first by said placement upon said smooth flat inclined surface of said first stacked tray into said flow of water to form said aggregate slurry, second by the formation of a column by the aggregate slurry as it is accelerated through said G force separator to form a vertical aggregate slurry column with each said component of said aggregate slurry separated by a respective specific gravity, and third, by the collapse of the column subsequent to the G force separator upon the vortex mat, with said gold particles trapped within said vortex mat and said remaining aggregates slurry discharged from said second end of said second stacked tray as waste.
