Precious Metal Recovery from Washout
An inexpensive but highly effective under-the-sink recovery system. This system utilizes two independent filtration devices:
The first, a prefilter, is a reusable coarse filter. It captures large objects like gemstones and rings.
The second filter is a replaceable, cotton-wound, 10-micron cylindrical filter. This filter is housed in a filter chamber. Since gravity doesn’t have enough force to push the water through the microscopic pores of this filter, the FiltraGold incorporates a powerful submersible pump. Max head for the standard pump is 10 ft. and 200 gph. Max head for the double pump is 10 ft. at 300 gph.
When the water level rises in the FiltraGold settling chamber, the pump’s integrated float switch activates, pushing the water through the filter. This filter captures all the particles of gold (down to 10 microns!) that would otherwise be lost down the drain. The filters are burnable to recover the gold.
In the average jeweler’s shop, this unit usually pays for itself within a week.$499.95 to $599.00

Precious Metal Recovery from Cyanide Solutions
Cyanide waters contain a surprising amount of gold. Even small amounts of solution (1 gallon, for example) are worth recovering the gold from. There are many ways to recover precious metals from cyanide waters (cyanide waters include bombing solutions, stripping solutions and plating solutions). Some of these methods include metallic ion exchange, resin ion exchange, chemical precipitation and electrolytic recovery. While the aforementioned solutions all work well, each have advantages and drawbacks.
The Shor Bombino Recovery System
This system is the simplest way to recover gold from cyanide waters. Simply clip your battery charger or rectifier to the Bombino, plug it in, and let it run overnight. You can run several gallons before you recover the gold (or just a few, if you prefer). To recover the gold, simply unscrew the top of the recovery chamber, remove the electrolytic foil, and melt. That's it. The Bombino includes a supply of Detection Pills and electrolytic foil.

- Tests for the presence of dissolved gold in cyanide waters. Test is sensitive down to 4 parts of gold per million parts of water.$11.95
- Got an even more limited budget? The Zap-Trap is simple but very effective for catching stones, rings and similar items. The stainless steel rim and screen are heavy enough to stay put and the fine mesh catches the smallest of stones. Zap-Trap fits virtually any sink drain from 11/8" to 2-1/2" in diameter.$5.95
