i-MeltorTM is a specially designed electrical arc furnace, combined either with a MHF (Primus), with a RHF (RedSmelt), or applied alone. When used in a single step process, it allows the recycling of various types of ferrous and non-ferrous metal containing by-products generated by the metallurgical industry (carbon or stainless steel EAF dust and sludge, ferronickel residues, Waelz slag, spent catalysts, copper slag,…).

The main characteristics of an i-Meltor furnace are:

  • central charging (between three electrodes),
  • high power rate (more than 1 MW/m2),
  • variable bottom stirring allowing both rapid smelting/refining and smooth settling.
