Sulfur in coal and its environmental impact from Yanzhou ...

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 the form of sulfide and H 2 S, which then react with O 2, water and other substances to change into vitriol, and in some places it may form acid rain. And they will impact water environment, acidify the soil and do great harm to plants and human health. In this paper, on the basis of the data from the Yanzhou mining …

What is Sulfide Mining? | Mining Action Group

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, environment, and communities.

Sulfur Mining | Processing Equipment | Flow Chart | Cases ...

Sulfur mining uses three different mining techniques: conventional underground methods, conventional open-pit methods, and the Frasch mining (or underground melting) method. In this process, hot water is forced into the sulfur deposit. The sulfur melts and is pushed to the surface where it is collected and allowed to cool and solidify, or shipped in molten form.

Introduction to Sulphur - The Sulphur Institute

Since early in the 20th Century, the Frasch process has been used as a method to extract sulphur from underground deposits, when it displaced traditional mining principally in Sicily. Most of the world's sulphur was obtained this way until the late 20th century, when sulphur's recovery from petroleum and gas sources (recovered sulphur) became more commonplace.
