Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water

The Frasch process is a method to extract sulfur from underground deposits. It is the only industrial method of recovering sulfur from elemental deposits. Most of the world's sulfur was obtained this way until the late 20th century, when sulfur recovered from petroleum and gas sources became more commonplace (see Claus process).. In the Frasch process, superheated water is pumped into the

The Frasch process was first used in 1894 in Louisiana, and in the early 1900s came into wide use in mining native sulfur deposits, especially deposits in the caprock of salt domes along the Gulf Coast of the United States. Frasch mining dominated sulfur mining in the U.S. for most of the 20th century, for many years providing more than 80

Apr 01, 2015 Sicily has vast sulphur deposits partly because it was once under the sea, and partly because it is a volcanic island fed with sulphur from deep within the earth. Some of the sulphur was taken out in rock form, but to extract the smaller traces as well, part of the mining process involved dissolving the sulphur into fluid

The first is the Frasch process, where sulphur is extracted from underground without mining it. In the Frasch process, underground deposits of sulphur are forced to the surface using superheated water and steam (to melt the sulphur) and compressed air. This gives molten sulphur, which is allowed to cool in large basins. Purity can reach 99.5%

Sulfur is one of the hazardous elements in coal. The concentrations of sulfur are relatively high in coal. The major forms of sulfur in coal are pyritic, organic and sulfate. Pyritic and organic sulfur generally account for the bulk of sulfur in coal. Elemental sulfur also occurs in coal, but only in trace to minor amounts. When coals are burned, leached and washed, sulfur will be released in

In the refined process design, which is aimed at reducing sulphur in the coal, all of the coal will be crushed to 6mm topsize before being passed through a similar series of cyclones, sieves and screens, however there will be an additional process to

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 the surface by means of compressed air.The mixture of sulfur and water is then discharged into
