Extracting metals from scrap 8
This Association for Science Education (ASE) publication about extracting metals from scrap was developed in association with ECR Ltd. This was a secondary copper refining company which was first established in Birmingham in 1807. Its origins could be traced back to Faraday's work on electroplating. ECR Ltd was then located near Walsall in the West Midlands and had recently became part of the IMI Group.
The booklet contained guidance for teachers and notes for students. It included activities suitable for both students aged 14 to 16 (O-level work) and for students aged 16 to 19 (A-level work).
