Metal refining - Import export

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.)

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.
