Technical Description

The Directive 2012/19/UE states the necessity of reducing the collection of electric and electronic wastes up to 2.5 kg/person/year and of re-using or recycling them between 70-90%. In order to give a solution to the problem, the present project provides a process to recycle NIB magnets from some of those kinds of wastes, which are one of their most valuable components and are not currently being recovered or recycled.

The NIB permanent magnets recycling line is constituted of the following modules:

  • Module I – NIB magnet extraction and separation. The main activity of this phase is to separate the maximum quantity of NIB magnets from the electronic wastes to be processed, in order to obtain magnetic material with as low as possible plastic and other material impurities.
  • Module II – NIB magnet purification. The second module will count with different steps for the purification of the NIB material by demagnetisation, size reduction and suction of the NIB powder.

Finally, the applicability of the NIB powder obtained will be confirmed by reusing it for magnets production at a demonstrative scale, since its final characteristics will satisfy the commercial ones.
