Pilot Study of using Resistivity-IP, Magnetometry and Slingram for Separation of Industrial Waste

A controlled experiment was carried out by doing geophysical measurements on a purpose-built heap consisting of two different industrial waste fractions, called NF ( non-ferrous metal) and SLF (shredder light fraction), from the recycling plant of Stena Metall in Halmstad, Sweden. The purpose of the experiment was to see if it was possible to distinguish the different types of material using geophysics. Resistivity-IP, magnetics and slingram were measured over the test heap. The results gave distinctly different signatures for the different materials. In conclusion the test shows a large potential for the tested methods for material characterisation of buried waste in connection with landfill mining.
