CLEAN : Helium: South Africa strikes new 'gold'

The video discusses the discovery of varying helium concentrations in gas, highlighting a significant find. It compares helium production levels with those in the United States, noting much higher concentrations. The gas treatment process, including purification and removal of carbon dioxide, is explained. The project is described as interdisciplinary, involving science, engineering, and logistics, and is dual-listed on two stock exchanges.
