Frasch process, method of mining deep lying sulfur invented by the German born American chemist Herman Frasch. The process involves superheating water to about 170 176;C (340 176;F) and forcing it into the deposit in order to melt the sulfur (melting point of about 115 176;C, or 240 176;F), which is lifted to

There are also some problems with this process if I am right The hot water used in this process causes thermal pollution, and may also contain some dissolved minerals. This may disrupt the chemical composition of local ecosystems, so one must recycle it. Depending on the make up of the area, remaining crypts can lead to earth subsidence.
