  2. Sicilian method - Wikipedia

    en.wikipedia.org/wiki/Sicilian_method

    The Sicilian method was one of the first ways to extract sulfur from underground deposits. It was the only industrial method of recovering sulfur from elemental deposits until replaced by the Frasch process. [1] Most of the world's sulfur was obtained this way until the late 19th century. [2]

  3. Mining in France - Wikipedia

    en.wikipedia.org/wiki/Mining_in_France

    Mining in France is based solely on the nature of the material, whether extracted from the surface or underground. These include fuels (coal, hydrocarbons, gas), metals (iron, copper) and a few other minerals (salt, sulfur). The inventory of mining resources is relatively well known for surface and subsurface deposits.

  4. Frasch process - Wikipedia

    en.wikipedia.org/wiki/Frasch_process

    The Union Sulphur Company was incorporated in 1896 to utilize the process. However, the high cost of fuel needed to heat the water made the process uneconomic until the 1901 discovery of the Spindletop oil field in Texas provided cheap fuel oil to the region. [6] The Frasch process began economic production at Sulphur Mines, Louisiana in 1903. [3]

  5. Mines of Paris - Wikipedia

    en.wikipedia.org/wiki/Mines_of_Paris

    The Paris area was a relatively flat sea-bottom during the early Cretaceous period: first in a deep-sea environment, then under a more agitated near-shoreline sea towards the end of the same period, Paris's largely silica-based sedimentary deposits became, under the action of pressure and the carbonic acid content of seawater, a thick deposit ...

  9. Supergene (geology) - Wikipedia

    en.wikipedia.org/wiki/Supergene_(geology)

    In ore deposit geology, supergene processes or enrichment are those that occur relatively near the surface as opposed to deep hypogene processes. Supergene processes include the predominance of meteoric water circulation (i.e. water derived from precipitation) with concomitant oxidation and chemical weathering.
