Process of Mining Sulfur. (open access)

Process of Mining Sulfur.

Patent for innovations in the underground fusion or Frasch process of mining sulfur, "which comprises conducting an appropriate fusing medium [such as hot water] into the formation containing the sulfur deposit and thereby melting the sulfur" (lines 91-95). Central to the innovations is the use of a compressed gas to "eliminate or largely reduce heat losses in porous rock and exhausted sulfur regions at the higher levels of the mine where the presence of the hot water is of no benefit so far as melting sulfur is concerned" (lines 55-60).
