Abstract
A method and an apparatus for analyzing a material, such as coal and iron ore, particularly with a view to identifying contaminants, is disclosed. The method and apparatus are based on the use of multiple (particularly dual) energy x-ray analysis with x-rays at different photon energies. X-rays are transmitted through a material and the detected x-rays are processed to produce an image of the material that combines together the separated images produced by the different photon energy x-rays. The combined image has enhanced contrast which minimizes the affects of non-compositional factors that otherwise would affect identifying constituents of the material.
