New statutory guidance, under the Industrial Emissions Directive, for non ferous metals has been published by the European Commission through the so called Seville process.  The best available techniques (BAT) concerns the production of the whole range of non-ferrous metals including copper, lead, tin, cadmium, precious metals, and cobalt and sets standards for the issuing of environmental permits. New standards for the production of carbon and graphite are also included due to their use in aluminum smelting.
