Precious metal refining - Import export

IKOI’s Prime Refining Unit is the result of ten years of experience in metal vacuum distillation. The technology is based on the physical principle of evaporation. It is a revolutionary green technology that can pre-refine precious metals without using acids or chemicals. This plant is specifically designed for small and medium refiners who need flexible, fast and sustainable way to process a variety of feedstocks, including dore bars, jewellery scraps and industrial waste with precious metal content. Prime Refining Unit removes silver and volatile elements from Au/Ag/Cu alloys using vacuum distillation technology. The exceptional capabilities are essential to reduce silver content on Au/Ag/Cu alloys without any chemicals and without any by-products. In this way, the alloy can be easily dissolved in a traditional Aqua Regia process or refined using gold electrolysis.
