Magnets for the recycling industry | Goudsmit Magnets

Through various real-world tests Goudsmit has determined that the 38HI technology performs best in the slag-reprocessing sector. This is due to the extremely high magnetic force and rotation speed. Particularly when it comes to the separation of heavy metals such as copper and brass, we achieve a significantly higher.

Separating and Recycling of Fe, Cu, Zn from Dumped Copper Slag .

sis of the components and recovery efficiency. Zinc silicates and zinc oxide in the slag were reduced to zinc violating in fume which could be captured as zinc oxide powder. The reductive product was pulver- ized to a particle size with diameter of 0.045 mm. Cu was then separated from iron by means of magnetic separation.
