Upgrading Zurik to Zorba: Increase Profitability and Reduce Fire Risk

April 19, 2022
Learn how the right separation equipment can upgrade Zurik to a more desirable and profitable Zorba fraction while also reducing scrapyard fire hazards.

Stockpiles of Zurik generate a significant fire risk due to the hot metals surrounded by flammable debris. Transforming relatively low-value Zurik material into a copper-rich, high-value Zorba product is ultimately easier to market and sell. In this white paper, you'll learn how the size reduction and liberation of Zurik are key to ensuring this process improves profitability.

By upgrading Zurik into Zorba, a processor transforms difficult to market, low-value Zurik that can be a fire hazard into a high-grade, highly sought-after, and copper-rich Zorba. This copper-rich Zorba also commands a higher price than standard Zorba and is also easier to market and sell. Additionally, this system creates a fine saleable stainless-steel product.

Equipment used within the Zurik to Zorba process consists of a ring mill; a small, drum-type magnetic separator; a high-frequency eddy current separator; and a stainless-steel magnetic separator.

Achieving maximum recovery and grade of the Zorba (+95%) requires the technology of an ultra-high frequency eddy current separator. Standard eddy current separators are only capable of recovering material coarser in size due to fewer frequency changes found in this type of magnetic circuit design and the larger size distribution.
