Maximising the value of aluminium: LIBS solutions for segregated alloys
In order to meet the growing demand for aluminium products, the industry needs solutions to upgrade mixed aluminium packages to segregated series/alloys. LIBS technology will be the primary enabler of this upgrade, allowing more recovered aluminium to reach its highest and best use, maximising its value.
Lighting the path: LIBS unravels elemental compositions
LIBS stands for Laser Induced Breakdown Spectroscopy, a technology that analyses material according to its elemental composition. A high-energy laser beam vaporises matter on the surface, creating a plasma which then breaks down with characteristic light emissions. The spectral analysis of these light emissions allows the elemental composition to be determined. These determinations allow aluminium series/alloys to be separated from each other.
LIBS technology is most often used in conjunction with X-ray transmission (XRT) technology, such as the STEINERT XSS T EVO 5.0 or STEINERT KSS XT | CLI. Specifically for post-consumer streams, XRT is used to remove heavy metals, compound materials and cast aluminium, leaving clean wrought aluminium.
How metal recyclers benefit from using LIBS technology
Rather than creating a mixed Zorba or Twitch package, processors can cost-effectively extract valuable wrought aluminium series/alloys from their streams. The segregated series/alloy packages can then be supplied to aluminium producers as a premium furnace ready package.
