A milestone in blister copper production

POLYCONVERT is the logical next step in converting – a new solution that implements improvements using the conventional Peirce Smith converter. This reactor type is still the most widely applied process for producing blister copper. It’s also common in nickel and PGM production process lines. Conversion takes place during the slag blowing stage as well as in separate final converting phases.

Now, PolyMet Solutions adds features that in particular improve the process efficiency and availability of the vessel, plus ensuring a longer service life. Your benefits at a glance:

  • Better lining in the tuyere, mouth, and off-gas offtake areas
  • ILTEC cooling of the under-bath tuyeres for significantly longer lifetime (up to > 1 year) - higher productivity
  • High-pressure tuyeres with higher oxygen levels
  • Less off-gas for smaller gas treatment plants
  • Lower OPEX
  • Optimized automation
