Looking for a solution to the "Black Sand" problem when mining dry placer gold? You have come to the right place! The MAG-ZIP rapidly separates magnetite from a continuous flow of dry placer gold concentrates, FIRST, before doing anything else!
It lightens the load by 30-50% in just a few minutes! The volume for the next step is smaller and lighter. The new MAG-ZIP technology saves enormous amounts of time and cleaning up concentrates has never been easier.
NOTE: While the MAG-ZIP can be set for running -8 mesh sand, we find that all "bird nesting" by twigs/leaves is prevented by screening to -12 mesh which runs fast, smooth, and more selectively. Besides, the vast majority of detrital magnetite has already been ground by nature to be below 12 mesh. Even the common lead bird shot is removed by the 12 mesh screen. So all units now run -12 mesh material.
The MAG-ZIP now (2020) uses weak magnets which are much more selective than strong magnets. The separated magnetite can be re-run to check for any stray particles, and re-runs are even faster! Two passes removes 90+% of the magnetite, and two quick re-runs makes sure it is pure magnetite. All four runs process 1 gal in 6 minutes, or less!
