China is the largest producer, with 48 million tons, followed closely by the United States, with 46 million tons [source: Salt Institute]. Salt is generally produced one of three ways: deep-shaft mining, solution mining or solar evaporation. Deep-shaft mining is much like mining for any other mineral. Typically, the salt exists as deposits in ancient underground seabeds, which became buried through tectonic .
Da Shu Xian, or Big Tree Country, in remote Sichuan Province is the site of a large sulfur mine, which produces up to 12,000 tons of sulfur a month.

Pyrite roasting and sulphur burning plants are built for the production of sulphuric acid. Whereas the burning of elemental sulphur is the main source for sulphuric acid, the roasting process is an interesting alternative once pyrite concentrate is available. In addition to these two applications, Figure 1 shows a wider variety of sources for the
Interesting Sulfur Facts: Sulfur has been in use since ancient times and is mentioned in the Bible and the Torah. Its name comes from the Sanskrit word "sulvere." One allotrope of sulfur was in used in China as long ago as the sixth century BC. Sulfur can serve as either an oxidant or as a reducing agent.

2014-3-29 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
Process water and effluents from mining operations treating sulfide rich ores often contain considerable concentrations of metastable inorganic sulfur compounds such as thiosulfate and tetrathionate. These species may cause environmental problems if released to downstream recipients due to oxidation to sulfuric acid catalyzed by acidophilic microorganisms.
Nov 18, 2015· All sources exclusive of ores are known collectively as sulfur-bearing raw materials. Sulfur is extracted from sulfur ores by a mining process (10–20% of world production) and a geotechnological process (90–80%). In the former, sulfur ores are mined in quarries or, much less frequently, in underground shafts.

A process for preparing a coal or lignite fuel that contains sulfur for combustion wherein reduced amounts of sulfur containing air contaminants are emitted from the combustion is disclosed. In the disclosed process, the coal or lignite that contains sulfur is first pulverized and is then mixed with a finely divided inorganic material.
This sulfur dioxide is an important byproduct of the lead refining process. It is captured at a separate acid plant and converted to sulfuric acid, which has many uses. After the ore has been roasted in this way, it fuses into a brittle material called sinter.
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%.
