Gold, Silver & Platinum
Shor has refining systems for gold, platinum and silver. Our gold and platinum system, the Simplicity, works without any acids. We strongly recommend the Simplicity refining system over any type of acid refining system. It is far safer, cleaner and easier. However, we carry supplies for acids systems as well. Our Storm Precipitant, for example, works very well in all acid type gold refining systems. It's far less expensive and has a virtually indefinite shelf life. Additionally, should you wish to construct your own acid type refining system, we have instructions for setting up and running.

To be blunt, if you don't already have one, you either weren't aware of its existence or you've made a costly mistake by not buying one before. It's that simple. There are over 8,000 units in use today and from just 2003-2008, over 6 metric tons of gold were refined in these refining systems. We estimate that our customers, by refining their gold themselves, have saved over $12,800,000 in just the past 2 years!
There is nothing in your shop that you can't refine yourself (though things like polishing sweeps do require some preprocessing).
Here's how it works:
Scrap gold is composed of several metals; gold, copper, zinc etc. Using a battery charger or rectifier and the Simplicity, your scrap gold is stripped (dissolved) into a special salt-water bath. A special ceramic cell prevents the metal from plating out of the water. To the water is added a powder which turns the gold, but not the other metals, back into solid form. While the pure gold drops to the bottom as small particles, the other metals remain dissolved. The water is then poured off and the fine gold particles are rinsed, dried and melted. The result is gold of 99.95% purity with losses of metal left dissolved in the waste water of less than .01 dwt. If desired, the other metals can be removed from the water by the addition of aluminum foil.

Shor Electrolytic Thumb Cell Silver Refining System
This is a purely electrolytic system, requiring a separate rectifier and working only with silver that is at least 90% pure before refining (Sterling silver is 92+% pure). Produces standard electrolytic grade silver of 99.95-9 .99% purity. Uses a dilute nitric acid for electrolyte, so some ventilation is required. Requires a rectifier of at least 25 amps.

Refining Silver Chemically
If you want to refine silver without buying equipment, you can do it chemically. You'll need baking soda, pancake syrup (Karo brand syrup, which is dextrose), drain cleaner (lye), water, buckets, wooden or plastic spoons and some other ingredients. Sounds like baking a cake, doesn't it? Well take precautions and do it out-of-doors because one of the "other ingredients" is nitric acid. We have complete instructions
Filters and Filtration Systems for Refining
For sink filtration systems, see Recovery Systems
Shor Buchner Filter Funnels
These flat bottomed filtration funnels are particularly well suited for rhodium purification and refining applications. When combined with a vacuum pump, Buchner funnels are the fastest, most efficient means of filtering most liquids [for standard filtration, see aspirator vacuum pump, for high volume filtration, see ARVT pump].
Shor Buchner filter funnels have a flat, perforated plate at the base of each funnel that is eminently suited for very rapid filtration (especially when combined with a vacuum pump [see the very inexpensive Shor aspirator vacuum pump below]). Shor Buchner funnels are designed to accept filter paper that is the same diameter as the inside diameter of the funnel. However, we recommend that, when using them to filter precious metals, use a filter paper of one size larger than the funnel's diameter. All Shor Buchner funnels, except the 5" diameter, sit flat on a tabletop.
We recommend the 5" funnel for rhodium purification and for relatively small filtration jobs. We recommend the 10" funnel for most filtration jobs. For very big filtration applications and for where a vacuum plate is required over the funnel, the 18 or 24 inch funnels are appropriate. 10", 18" & 24" funnels have removable, perforated plates for easy cleaning.
Vacuum Plates and Gaskets for Buchner Funnels
Allows for hands-free filtering when using a Buchner funnel with a vacuum pump. Can completely eliminate acid fumes during the filtering process. Because different systems require different hose sizes, the plates and gaskets come undrilled and without hose fittings. See below for sizes and prices.
Buchner filter funnels have relatively large holes. When working with powerful vacuum pumps, the pressure can punch holes in even double layered heavy duty filter paper. Filter fabric is used to underlie the filter paper, providing both support and the ability to catch particles of precious metal that pass either through or around the filter paper.
|Shor filter fabrics are plastic based and hold up well under acids for repeated use and washings. Comes standard in 25 micron size but is also available in several different micron sizes. See below for sizes and prices.|

Shor Aspirator Vacuum Pump
This is a very small, inexpensive vacuum pump, yet it provides a quite respectable 27"Hg vacuum. Requires running water with good pressure from a tap or garden hose to operate.
Shor Acid Resistant Vacuum and Transfer (ARVT) Pump System
|In the acid method of refining gold, the acids and the fumes that are generated by the acids are exceptionally corrosive (less than 1 second of exposure is all that is needed to cause a reaction that will rust even the highest grades of stainless steel). Despite this (and because of this), it is necessary to use vacuum and transfer pumps to move and help filter this acid. Most transfer pumps cannot work without priming (a dangerous and inadvisable procedure when working with acid). Vacuum pumps, because they are made from metal, corrode within days or weeks. The Shor ARVT Pump is different. It19.959;s made for daily use in both transferring and filtering acid in large volume. This is the heart of our acid refining systems (our smallest aqua regia [acid] system will handle 500 ounces of gold a day). The ARVT Pump will transfer up to 1 liter of acid every 2 seconds and develop an incredible vacuum of 29.5 inches of mercury (almost an absolute vacuum!). When used with a vacuum plate over your Buchner filter funnel (see Shor Buchner funnels), you can both transfer and filter your acid in one step without ever handling the jars of acid ARVT Pumps sold 19.950 years ago (when we first developed it) are still in daily use.|
The ARVT Pump will deliver decades of trouble-free service when properly maintained with regular replacement of the "O" rings and Cap Seals. If you do a lot of refining with acid, this pump will make life a lot easier (and safer) for you. Maximum setting will move 1 quart of acid every 2 seconds. You can adjust the amount of draw by raising or lowering the stroke adjustment bolt.
When used in combination with a Buchner filter funnel, gasket and vacuum plate, you can do all you filtering and acid moving operation without ever pouring any acids, ever!
This pump operates by air pressure and requires a minimum compressor size of ½ hp.
