Abstract
The invention relates to a method and a system for separating dust-containing material mixtures which contain fibers, preferably glass fibers, and have heavy metal (SM) and/or precious metal (EM) from the process of recycling electric or electronic devices, wherein the method has at least one step (S1) of mechanically releasing particles from fiber-containing mixed material agglomerates in a dry manner and at least one step (S2) of mechanically releasing fiber-containing mixed material agglomerates in a dry manner.
Claims19
A method for separating dusty material mixtures containing fibers, and further comprising heavy metal and/or precious metal, from recycling of electric or electronic devices, the method comprising:
- at least one step (S1) for mechanically and drily detaching particles from mixed material agglomerates containing fibers;
- and
- at least one breakup step (S2) for mechanically and drily breaking up the mixed material agglomerates containing fibers,
- wherein
- a fractionation according to particle sizes is carried out simultaneously in the step (S1) of detaching particles,
- and/or a fractionation according to particle sizes is carried out simultaneously in the breakup step (S2), fractions produced in the method being subjected to smelting or supplied to a refinery wherein, in at least two fractionating steps (S1, S3, S4, S5) producing a fraction of particles less than 100 μm in size in one spatial direction, the respective fractions are sorted out or provided for smelting or for transfer to the refinery.
