Pyrotek, which is a global engineering leader and innovator of technical solutions and integrated systems design, works with nonferrous metals companies world-wide to help improve performance of high-temperature processes. Pyrotek products and solutions are in employed in automotive, aerospace, rail transportation and high-tech manufacturing. For lead‒acid battery plants, Pyrotek produces a lead-recovery system that enables the operator to recover lead metal from dross or skimmings in-house via a thermomechanical process. The typical recovery rate from skimmings is between 60 and 80 wt.%. This metal has significant value. Moreover, any residue of lead-oxide powder residue can serve as feed material for smelters. With plants that are processing antimonial alloys, the alloy remains in the recovered lead. An overview of the Pyrotek lead-recovery system will be presented, together with several experiences with the equipment at battery plants and the subsequent benefits that end-users have reported. The system has also replaced old remelt furnaces due to its energy efficiency and very clean operation. Whilst processing, the system does not require a dedicated operator nor a standby attendant. Many lead-processing plants now use the Pyrotek technology every day and, with the increasing cost of metal, the advantages associated with in-house lead recovery are increasing.
