The European Commission proposed the Critical Raw Materials Act in March, a centrepiece of EU strategy to allow it to compete with the United States and China in making clean tech products.
The proposal said the European Union should extract 10%, recycle 15% and process 40% of its annual needs by 2030 for 16 "strategic raw materials".
The European Parliament and the Council, the grouping of EU governments, needed to agree on a common text.
