Precious metal - Import export

Manufacturing plants, machines, technologies and engineering services on PMs metallurgy, casting, pyrometallurgy and physics separation of pure and alloyed Precious Metals.

Induction static melting furnace for manual graining production of precious-metal alloys in graphite mixture crucible, with automatic temperature control. Our product range includes the following type of furnaces: - Tilting induction furnace - Static open crucible - Static vacuum/controlled atmosphere crucible IKOI's metallurgical process knowledge allows the selection of the most approriate technology and crucible material for each application.

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.)

Continuous electric induction system furnace straight type for the production of gold or silver bullion in controlled atmosphere, suitable for the working with graphite ingot moulds. ADVANTAGES OF FLAMESS TUNNEL Significant reduction of rejects due to increased quality of the bars Better for the environment (Green technology) Cancellation of precious metal losses (loss of weight: 0,01 g/kg) Safer for the operators Significant reduction of electricity consumption Considerable reduction in radiant and convective heat loss Significant reduction of the labour time for the production Not specialized skilled workers requested Fast production times Increasing of the material turnover Excellent surface finishing thanks to fss system - flat & shine surface system
