This BREF covers the techniques for the production of both primary and secondary non-ferrous metals. In particular, eight groups of metals with similar production methods are dealt with in more detail in the document:
• Lead and/or Tin
• Zinc and/or Cadmium
• Precious metals
• Nickel and/or Cobalt
• Carbon and graphite electrodes. The production of carbon and graphite anodes is included because of the production of anodes at some aluminium smelters as an integral part of the production process.
