GERMANIUM
Not too long ago this relatively rare metal was a laboratory curiosity. W h a t to do with it? Today, it's the heart of the tiny transistor —the latest ___ giant of electronics! What's the connection between Sulphur and Germanium? ^ M There are two, in tact, one is man-made, ^ ^ involving the routine leaching of Germanium ores with Sulphuric Acid prior to tetrachloride distillation. The other takes advantage of a peculiar property of the natural mineral, Germanium Sulphide. This mineral can be volatilized and then sublimed, providing an effective method of separating the Germanium from gangue material. The process is called "Concentration of Germanium by Sulphide Sublimation". Again Sulphur, through its major derivative, Sulphuric Acid, and a natural sulphide play an important role in our ever-expanding economy. It is difficult to find many items in the broad chemicalmetallurgical field that do not somewhere along the production line make use of Sulphur or a derivative.
