Abstract
A method for remote analysis of a mixture of materials where one of the components has thermal characteristics different from the other components. In a preferred embodiment, tar sands on a moving belt or dropping into a hopper are irradiated with infrared radiation and the radiant thermal flux of the heated tar sands is remotely detected and measured to determine bitumen content.
