Characterizing the urban mine and mining waste
SIG meeting for sampling and analysis; February 13th, 2017
Practicalities of sample preparation and chemical analysis for complex products and waste materials
Reference methods for chemical analysis that produce comparable results are an important prerequisite for prospecting secondary raw materials (SRM) in the urban mine. Standardized methods already exist for well-established matrices, such as ores or soils. This is not the case for complex solid products like Waste Electrical and Electronic Equipment (WEEE), waste batteries, or end-of-life vehicles (ELV) which have both high mass fractions of metals and a large number of elements (smartphones consist of more than 60 elements), in combination with sometimes high contents of organic materials from plastics. Hence, comparability of literature data from different studies is not assured.
A dedicated workshop, jointly organized with Aurubis AG, will bring together practitioners across Europe and will allow in depth discussions about state of the art in CRM analysis and quality assurance.
