Abstract

The invention is direct to a method and an apparatus for the bulk determination of scrap metal content, said method comprising the steps of providing a scrap metal input; preparing said input for submission to a bulk scanning apparatus; scanning at least part of the scrap metal with a bulk scanning apparatus to determine the composition of the scrap metal; and securing said scrap metal from the step of providing the scrap metal input to the step of scanning at least part of the scrap metal. Said apparatus comprises a scanning container together with a low-intensity neutron scattering device, a laser cutting device and/or magnetic sensing device.

IPC Classes  ?

• G01N 21/00 - Investigating or analysing materials by the use of optical means, i.e. using sub-millimetre waves, infrared, visible or ultraviolet light

• G01N 21/71 - Systems in which the material investigated is excited whereby it emits light or causes a change in wavelength of the incident light thermally excited
• G01N 23/204 - Measuring back scattering using neutrons
• G01N 27/72 - Investigating or analysing materials by the use of electric, electrochemical, or magnetic means by investigating magnetic variables
• G01N 21/85 - Investigating moving fluids or granular solids
