Germanium in Kansas Coals

Abstract

A detailed spectrographic method for determining the germanium content of coal is described and the results of analyses of twenty Kansas coals from 117 different locations are reported. No definite conclusions are made as to geographic or stratigraphic variation in germanium content. The concentration of germanium in the coal ash ranges from .0018 percent to .0575 percent, and in the total coal from .0006 per cent to .0116 per cent.
