Although Wohlwil process is over a century old, still it is the only process that will refine gold to highest purity of 99999+ We are offering these systems in our own modifications eliminating up to 10% unrefined gold per cycle.
Wohlwill Process Equipment Makes Your Gold 99999
Refining gold to the highest degree always requires a two step purification process. It is virtually impossible to refine gold to 99.99% or better quality in a single step when your starting material is less than 95% purity, regardless of what any manufacturers claim. Most gold from low grade feed material can be refined to 98% - 99.5% purity, depending on its composition.
For high purity refining, the Wohlwill process is used as a second step. With feed material over 98% this protocol is capable of providing 99999 purity.
For refining to 99999 purity we offer a two step version of our REFINEIT system that will produce extremely high grade gold, where the first step is carried out using our REFINEIT system process and a second using the Wohlwill process, all using our REFINEIT machines.
