sulphur mining process in india

Sulfur Mining Process From the late 1800s to the end of the 20th century, the Frasch process of sulfur mining was commonly used. This involved forcing super-heated water into a sulfur deposit so the sulfur would melt and come up to the surface by way of compressed air. Get More.

Frasch process | mining | Britannica

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 ...

nickel processing - Extraction and refining | Britannica

Being free of sulfur, laterite nickel deposits do not cause a pollution problem as do the sulfide ores, but they do require substantial energy input, and their mining can have a detrimental effect on the environment (e.g., soil erosion). The range of process options is limited by the nature of the ore.

In October 20, 1890, he took out three patents for the process and interested two associates, Frank Rockefeller and F.B. Squires in the sulfur mining process. Dr. Frasch then contacted the owners of the American Sulphur Company and proposed a fifty-fifty deal; his process and their land. The new company was named "Union Sulphur Company."

Copper Mining and Processing: Processing Copper Ores ...

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

Environmental Risks of Mining

Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.

1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.

Sulphur Production & Uses - Nuroil

Native sulfur deposits in Louisiana, Nevada, Texas, and Utah were mined with conventional mining methods. Domestic sulfur production, including mined elemental sulfur and pyrites, supplied about one-quarter of the U.S. sulfur demand of about 415,000 tons. Most sulfur and pyrites, domestic and imported, were used to produce sulfuric acid that ...

Heart of Louisiana: How the city of Sulphur got its name

The "frasching process" made sulfur mining possible in the swampy earth of Southwest Louisiana, where digging mine shafts was difficult and deadly. "On Christmas Eve was the first time they successfully mined sulfur using his process," Trahan said. "They would drill down to the deposit.

Sulphur, Sicilians, and the Exodus to the USA – The ...

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.

AP-42, CH 8.13: Sulfur Recovery

Sulfur recovery refers to the conversion of hydrogen sulfide (H2S) to elemental sulfur. Hydrogen sulfide is a byproduct of processing natural gas and refining high-sulfur crude oils. The most common conversion method used is the Claus process. Approximately 90 to 95 percent of recovered sulfur is produced by the Claus process.

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%.
