STC Innovative processes for paste desulphurization (U4Lead) and for hydrometallurgical production of nanostructured lead oxides (Lead3)

Agenda for
21-23 June

Alberto Bergamaschini and Sabrina Urgese
Commercial Director & Business Developer / Marketing and Sales Assistant, STC srl , Italy
The STC presentation is focused on the benefits of two patented process owned by STC : U4lead is an innovative process for the paste desulphurization using an amino compound instead of the more traditional process which uses caustic soda or soda ash. The comparison and the advantages are discussed. Once the paste is desulphurized and Lead carbonate is obtained one interesting alternative to the traditional smelting in rotary furnace is the production of pure nanostructured lead oxides through the Lead3 hydrometallurgical process. Test result will be presented.
