ABSTRACT:
Bitumen content of tailings or sludge obtained from processing of tar sands is quickly determined by a two step process wherein (1) clay mineral content is determined by adsorption of methylene blue and this value correlated to adsorbed organic material, (2) the content of total organic material is determined by a chromic acid oxidation, and the difference in these values gives the bitumen content.
