5. Metal recovery from effluents
The non-renewable nature of the resource and the ever-increasing use of metals in manufacturing industries such as mechanical, electrical and electronic engineering are naturally leading to the development of metal recovery and recycling as part of a circular economy. It is interesting to compare two preferred sources: geological mines and urban mines ® (city mines) (see table 16 ) .

Bibliography
Standardization
Numerous international and French standards exist for specific assay methods by metallic element or analytical technique. They are constantly evolving, thanks to the development of recent techniques (mercury determination by atomic fluorescence spectrometry in 2002, application of inductively coupled plasma mass spectrometry (ICP-MS) in 2005) and the improvement of older ones (trace element determination by graphite furnace...
