Portovesme has been applying the Kivcet technology at its industrial site since 1987. Different scenarios in the lead market occurred over the past three decades and Portovesme adapted the design of the furnace in order to be able to treat different kinds of lead bearing materials. This paper provides an overview of Portovesme's Kivcet design and experience in smelting various lead concentrates, as well as lead recycles and Zn leaching residues coming from different sources. The success of the Kivcet process is proven when installed within an integrated zinc-lead complex like Portovesme. It is in fact possible to optimize the recovery of metals inside the plants and consequently minimize the volume of residues dumped. The last changes made in 2012, coupled with a new Continuous Drossing Furnace (CDF), increased the feed flexibility and the Kivcet at Portovesme is nowadays smelting a wide range of complex materials, while keeping the same ability to recover all of the valuable metals into saleable products.
