In the mining of sulphur through the employment of the well known Fra'sch system, a tubular well is drilled into the sulphur bearing stratum or formation, and pumps are utilized to force hot water into the sulphur stratum so that the sulphur is melted and flows toward the mouth of an eduction pipe through which it is pumped to the surface in liquid form.

Pollution from Mining

Acid mine drainage results from the outflow of water from metal mines, coal mines, or other areas in which the ground has been disturbed. Metal salts, such as Fe+2, are oxidized upon contact with air to more highly acidic aquo species. Sulfur containing molecules are air oxidized to sulfuric acid.

In the method presented in this paper, sulfate sulfur is converted to barium sulf ate by digesting the sample with an acidified solution of barium chloride in an inert atmosphere to prevent oxidation of any sulfide sulfur. Any insoluble sulf ate present remains with the precip­ itated barium sulfate.

Terminology. Mine tailings' size and composition depends on the mining method. For hardrock metal mines, tailings are usually a very fine mud or powder, which is left over after ore is crushed and valuable minerals are extracted from it. Tailings may also contain chemicals used for mineral extraction. Tailings are distinct from "waste rock",...
