Frasch process, method of mining deep-lying sulfur invented by the German-born American chemist Herman Frasch. The process involves superheating water to about 170 °C (340 °F) and forcing it into the deposit in order to melt the sulfur (melting point of about 115 °C, or 240 °F), which is lifted to

Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (ndida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year.

By value of annual production, sulfur is the state's fourth ranking mineral and accounts annually for about 3 percent of its total mineral production value. Texas at times has produced more than 90 percent of the nation's sulfur. In 1954 Texas sulfur production by the Frasch process amounted to 3,450,000 long tons valued at $75,100,000.

The Sulfur Mining Process. From the late 1800s to the end of the 20th century, the Frasch process of sulfur mining was commonly used. This involved forcing super-heated water into a sulfur deposit so the sulfur would melt and come up to the surface by way of compressed air.

The second Frasch-process mine opened in 1912 in Brazoria County, Texas. The Gulf Coast came to dominate world sulfur production in the early and middle 20th century. However, starting in the 1970s, byproduct sulfur recovery from oil and natural gas lowered the price of sulfur and drove many Frasch-process mines out of business.
