Eriez has introduced a Copper Reduction Circuit designed to help steel mills process scrap more efficiently. By utilizing ballistic and magnetic separation, the system reduces copper levels to under 0.20 percent.
Why it matters
Steelmakers often struggle to remove copper from the melt during production. This technology streamlines the separation process, allowing for higher-quality material outputs.
The system utilizes a Shred1 Ballistic Separator to classify 75 percent of material as premium No. 1 fraction, while a Magnetic Scrap Drum removes 1 to 3 percent of nonferrous debris. Roughly 15 percent of the original infeed reaches the picking station.
The players
Eriez
Eriez is a manufacturer based in Erie, Pennsylvania, known for its advanced magnetic and sensor-based separation technologies.
The details
The circuit combines ballistic forces and magnetic attraction to sort shred into distinct streams. This dual-action process polishes the material, ensuring that nonferrous contaminants are removed before reaching final processing stages.

The Big Picture
This circuit advances the Shred1 Ballistic Separator technology by automating the removal of nonferrous contaminants that traditionally complicated scrap recycling. The integration marks a shift toward highly precise material purification, effectively replacing manual sorting with automated ballistic and magnetic protocols.
Refined scrap processing allows steel mills to produce higher-quality metal, potentially reducing energy consumption during the refining process. This improvement in material purity can lead to more efficient manufacturing of consumer products that rely on high-strength, low-copper steel alloys.
The takeaway
Advancements in separation technology allow manufacturers to reclaim more value from recycled materials. By lowering copper impurities, mills can maintain stricter production standards while minimizing waste.
