    Frasch process

    The Frasch process is a method to extract sulphur from underground deposits. It is the only industrial method of recovering sulphur from elemental deposits. Most of the world's sulfur was obtained this way until the late 20th century, when sulfur recovered from petroleum and gas sources became more commonplace. In the Frasch process, superheated water is pumped into the sulphur deposit; the sulfur melts and is extracted. The Frasch process is able to produce high purity sulfur.
