process of sulfur extraction from mineral deposits

SULFUR INDUSTRY The Handbook of Texas Online Texas

In 1891, a liquid extraction process invented by Herman Frasch was patented. In the Frasch process wells are drilled into deposits, the sulfur is melted with superheated water, and the molten sulfur is forced to the surface. The process did not prove practical because of the high cost of heating fuel.
