Extraction Of Helium Research Articles

Helium in the United States

ONE of the projects started in the United States during the war and since continued, is the extraction of helium from natural gas for use in balloons and dirigibles. In 1907, Cady and McFarland published a report on the presence of helium in a number of natural gases, mainly from Kansas, U.S.A. Some of the samples tested ran as high as 1½ per cent. helium by volume, although the majority of them were considerably below this figure.
