Steel Wool Silver Recovery Canisters Featuring Steel Wool Inserts.
How These Canisters Work...
As used fixing solution or wash water passes through the steel wool fibers, the silver ions in solution exchanges with the iron ions in the steel wool. The silver ions combine with sulfur and forms a precipitate that falls to the collection chamber in the bottom of the canister as 'sludge'.

The 'up-flow' design of the Rotex canister allows most of the precipitate to fall freely and not plug up the steel wool. Some of the silver-bearing precipitate is likely to adhere to the steel wool fibers and both the used steel wool and sludge are smelted in a reverberatory furnace to recover the silver. A single pound of steel wool may recover as much as 6 to 9 Troy Ounces of silver in normal operation.

Time of contact between the solution and the steel wool is very important for the exchange to take place. If the solution passes through too quickly some silver will not be trapped. A very high flow may even wash out the sludge. At the recommended flow rates, solution entering the steel wool at 50ppm (parts per million) also defined as 50 mg per litre - will usually give up approximately 95% of its silver and exit the canister well below 5 ppm.

Where environmental protection requires that the solution be stripped to 1 or 2 ppm, a second canister is connected in series to the first. Use a taller model for the secondary canister.

Smaller bucket is 3.5 gallons, 10.25" high, larger bucket is 5.0 gallons, 14.25" high. Handle folds down when not in use so if you're limited in space can be left down until needed.

Type M (Medium Grade) - For use with other black & white fixers without 'Part B' hardeners; C-41 Fixers and stabilizers; fixers for microfilm and Cine films; wash water.
