How It Works
The 17-inch Gold Magic® pan is computer designed for maximum gold recovery. Gold starts to separate from other material and move into the removable center cup in 30 to 45 seconds.
The pan is set at an approximate 45° angle. When prospecting wet, the water line needs to be set at the center of the pan. As the pan rotates, you shovel sand and gravel material into the pan at the 3 to 4 o'clock position of the pan.
The larger, low density materials will be expelled from the pan while the heavier, smaller materials (black sand, gold, platinum, and gemstones) will be carried up the spiral riffle into the removable concentration cup.
This is the primary classification area - all materials, sand, gravel, etc. (wet or dry) is shoveled into this area. Large size and most low specific gravity materials roll out of the pan as it rotates. Heavy weight materials (gold) sink to the lowest point at the joining of riffle and the pan (1-C) and commence rotating toward areas (2,3,4).
This is the riffle transition and large nugget recovery area. Nuggets too large to spiral up the riffle in area (3) into concentrate cup (4) will remain in area (2) until visually sighted and removed.
This is the secondary classification area. The heavy material, (high specific gravity) like gold, platinum, flour gold and black sand, will continue to travel at the low point where the riffle joins the pan (1-C), to area (4). Most light (low specific gravity) material falls from the riffle in area (3) and it's ultimately ejected from the pan.
Final classification area. Here you immediately see the results. The gold settles in the removable cup (4). As it continues to tumble wet, it is "cleaned up" with a gentle splash of water and is ready for removal. Dry gold concentrate is removed from here for final wet cleanup.
There are 69 agitator knobs in the primary processing area of the Gold Magic pan. These agitator knobs move through the material in rapid succession causing it to mix and tumble, all designed to quickly get the gold into area (1-C).
As the pan rotates, sand and fine gold will be carried to approximately the two o'clock position. At which time gravity takes over and the materials fall from area (6), across the agitators (1-B) into area (1-C). Designed to keep the flour gold below the riffles and rotating to the concentration cup.
The locking system allows the third leg to be locked in at any angle.
