Introduction
In order to support EN 50625-1, Collection, logistics & Treatment requirements for WEEE - Part 1:
General treatment requirements, covering treatment of WEEE, it is essential to include normative
requirements, such as management and technical requirements and target and limit values, into a
document that is able to be revised to take into account both practical experience and changes in
treatment technologies.

1 Scope
This Technical Specification addresses the processes regarding the recycling of copper and/or
precious metals contained in WEEE and fractions of WEEE.
NOTE 1 For the treatment of WEEE EN 50625-1 applies.
This Technical Specification relates to the chemical and metallurgical processes used for the recycling
of copper and/or precious metals contained in WEEE and fractions of WEEE, thereby differentiating it
from manual/mechanical processing (see Annex A).
All chemical and metallurgical processes are included up and until the output materials will be used for
their original purpose or for other purposes or will be finally disposed of.
NOTE 2 The main precious metals concerned are gold, silver and palladium.
NOTE 3 The majority of the WEEE volumes that are processed by final treatment operators consists of
fractions of WEEE (e.g. circuit boards) containing copper and/or precious metals, however there may be whole
small WEEE that can be treated directly in final treatment (e.g. USB sticks).
NOTE 4 Chemical and metallurgical processes are processes in which a chemical reaction takes place for
example: pyrolysis, smelting, refining, solvent extraction, ion exchange, leaching/dissolution in water acids or
base, precipitation, cementation or pressure leaching. They differ from mechanical / physical processes such as
sorting and separation based on physical properties (e.g. density, magnetism, colour) and size reduction
processes such as shredding and grinding.
NOTE 5 In general, these final treatment facilities are covered by the IED 2010/75/EU, e.g. copper smelters or
refiners.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
