Mixing and separating for recycling of metals such as contained in electronic waste requires to master dissolution, formulation of complex fluid, selective extraction and finally re-mixing of electrolytes in order to obtain high performance recycled material with new economic value.

Download the syllabus for the 2010/2011 Separative Chemistry course in pdf format.
Since October 2009, a weekly course in Separative Chemistry has been taught on Thursday from 1:30 to 3:00 at the ICSM (unless otherwise specified). This course is part of the ED 459 (Doctoral School) M3 programme (or Ph.D. 1), and should be recognised by the other doctoral schools that were part of the MESR’s radiochemistry workgroup. Graduate students working at Marcoule who attend this course on a regular basis will be given credits (whether or not enrolled at the ICSM). This course may be prolonged by seminars focussing on one particular point of separative chemistry given by guest speakers.
