Our solutions in primary nonferrous metals smelting
There are several conventional and unique processes available for the primary smelting of nonferrous metals, such as bath smelters (TSL type), flash furnaces, electric furnaces, tilting furnaces, rotary furnaces, as well as shaft furnaces. What these furnaces have in common is that they require a modern control system, advanced cooling/lining concepts, low-emission burners, and a robust furnace design. SMS group offers a wide range of improvements and optimizations for these furnaces. Additionally, SMS group supplies TSL furnaces for the recycling of metal-containing waste material.

BlueSmelter
Furthermore, SMS group has developed its own primary smelting technology, the so-called BlueSmelter. The BlueSmelter is an innovative bath smelting technology, which processes primary raw materials for nonferrous metals production, such as copper concentrate and other ores for the production of zinc, lead, tin, and other metals. The BlueSmelter was designed to process a wide range of copper and precious metals containing secondary raw materials, with a focus on low qualities and high organic content but with significant monetary value. The improved bath smelter furnace enables maintenance-free blowing of the media via the patented SIS injectors, which provides better turbulence for rapid reactions in the vessel. SMS group successfully conducted pilot-scale tests to demonstrate its technical feasibility.
