We are a globally renowned provider of comprehensive metal refining solutions, originally recognized for our Vacuum Distillation Units (VDUs), and now offering an expanded range of cutting-edge equipment. With a legacy of refining 25% of the world’s tin and lead using vacuum distillation furnaces, we have propelled our expertise to encompass a diverse array of refining processes.

From Vacuum Distillation Units (VDUs) that refine tin and lead to 99.9% purity, to Fuming Furnaces designed to unlock trapped metal value from slag piles, our repertoire has expanded extensively. Our Electric Arc Furnaces employ a unique dual-port system for discharge of crude tin and slag in the smelting of tin and other materials, while Impurity Removal Kettles facilitate the separation of impurities from molten tin.

Our Crystallizers automatically controlled cooling to segregate impurities such as lead and bismuth, concentrating valuable elements like silver and gold in the liquid state, without necessitating additional reagents or oxides. Additionally, Liquation Furnaces facilitate the separation of tin from lower melting point impurities, ensuring enhanced purity in the final product.

A hallmark of our services lies in our unparalleled manufacturing of 90% of the world's commercial vacuum distillation units. These units are favored by some of the largest mines and secondary refineries globally, not only for their efficiency but also for the minimal operating costs (OPEX) they incur. Furthermore, our commitment to environmental responsibility shines through, as our workplace emissions remain significantly below the OSHA limits.

Our legacy of research, spanning over six decades and yielding over 200 scientific papers, underscores our mastery of metal separation in various alloy compositions. This treasure trove of knowledge empowers us to offer customers precise operating conditions for a wide range of alloys, all based on our comprehensive technical database.

Installation is where our dedication truly shines. We manage the installation of all equipment, standing steadfast until smelting and refining objectives are resoundingly achieved. This unwavering commitment ensures that our customers' endeavors are met with unwavering success across the entire spectrum of materials and processes we now offer.
