Basic Materials

The basic raw materials for HCM S.A. “Miasteczko Slaskie” operating the ISP technology are primary materials such as bulk concentrates as well as Zinc oxides.

Sulphide bulk concentrates are produced by processing naturals Zinc sulphide and Lead sulphide ores extracted in mines in Australia, Canada and Poland.

Oxide materials are generated mostly through processing Zinc residues such as steel dusts and other containing Zinc.

Major oxide materials are:

  • Waelz Oxide
  • Conditioned oxides (containing also Lead)
  • Hydrooxides generated in Zinc hydrometalurgy
