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.

ALS® – Acidless Separation® by IKOI is a revolution in the metal refining industry. It achieves silver and gold separation without any chemicals. This Green Technology has obvious benefits for the environment and the communities, as well as a positive effect on the economics of the industry. ADVANTAGES OF ALS®: No use of chemicals. ALS® is a real Green technology No Precious Metals losses Fast process Safety and security No need of Precious Metals lock-up Easy metal control and accountability at every step of the process Easy to use Flexible (it can process a wide range of alloys) Low OPEX Low Maintenance No need of additional equipment (scrubbers, filters, waste water treatment plants etc.)
