Gold and Silver refining is a series of operations to achieve pure metal (gold and silver), starting from different feedstocks (dorè bars, jewellery scrap, WEEE material or others).
The series of process necessary to refine precious metal are mostly a combination dissolution and precipation using acids or eletrochemical deposition.
IKOI is the only company providing pre-refining technology based on vacuum distillation of feedstocks into treatable alloys for electrolitic plants or Aqua Regia plants.
