Jan 14, 2017· Brief description of tools, items and the beginning processes of reclaiming gold by saltwater electrolysis.
Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction.
Just as water is an effective solvent of many substances because of its chemical composition, mercury's atomic structure makes it an effective solvent of most metals. This, combined with its low boiling point, make it useful for extracting gold from ore in a process of amalgamation and distillation.
Now talk about the recovery. Only one gold extraction method cannot be used to recover gold from all parts of computer. Nitric process or CN process can be used to remove gold from gold plated/polished pins and connectors. From CPUs we can recover gold through aqua regia.
This unit can recover all precious metals (anions) existing in the pregnant solution with the accumulate sequence on the cathode. this base model is suitable for small scale operations of either e-waste recycling or small gold mine operations (after extensive leaching of either gold ore concentration or loaded active carbon).
