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.

Frasch process Wikipedia

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 wateris pumped into the sulfur deposit; the sulfur melts and is extra

Sulfur Mining & Processing: What to Know General Kinematics

The 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. During the latter part of the 20th century, mining or recovering sulfur

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

Sulfate Discharge: Measurement & Removal Saltworks

Jun 17, 2020· In mining, metals are often extracted from minerals containing sulfur—and processing means oxidation to sulfates. Although not generally very dangerous to humans, moderate levels (250–500 mg/L) of sulfates in drinking water are associated with an undesirable taste, and higher levels can cause illnesses such as diarrhea (>1000 mg/L).

Sulfide Mining, Mining Methods, Techniques, Copper, Zinc

Mining impinges on the groundwater table level. The mine acts like a massive well by pulling in water from the neighboring area. To keep the mine in process, the water has to be incessantly pumped out of the mine. This process is known as dewatering.

DECOMPOSITION OF METAL SULFATES A SO2 -SOURCE

For the decomposition of iron sulfate it is common practice to use fluidized bed reactors. Following table shows the Process of a typical iron sulfate decomposition plant: o Number of salt feed points 2 o Bed cross section area 20 m² o Bed height 1.4 m o Temperature 800 900°C o Number of oil feed points 15

Copper Mining and Extraction Sulfide Ores

The roasting process: changes some of the CuFeS 2 to copper oxide; removes some of the sulfur as sulfur dioxide; This is done by heating the concentrated ore from froth flotation. It is heated to between 500 °C and 700 °C in air. The product from the roaster is called calcine. It is a solid mixture of oxides, sulfides and sulfates.

A New Process For Sulfate Removal From Industrial Waters

This process is a true reduction of total dissolved solids (TDS) in that all chemicals added for treatment are precipitated during the reactions. Operating costs for near-complete sulfate removal using the process, which has been demonstrated successfully for many industrial waters, are estimated at $3 to $6 per 1000 gallons treated.

BEST MANAGEMENT PRACTICES TO MINIMIZE SULFATE

weathering process, sulfates will be generated regardless of management practices in place. Mining operation permits recognize that some amount of sulfates will be discharged by the mining, processing, and waste management. The permit approval is based on demonstrating that the discharges of sulfate and chloride will be minimized

Acid mine drainage Wikipedia

Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks

Sulfur Mining in Indonesia BORGEN

Jul 07, 2014· The antiquated process of sulfur mining in Indonesia poses extreme health hazards and safety issues for the miners. According to the BBC, 74 miners have died of work-related incidents in the past four decades. Many of these deaths have been due to toxic fumes billowing out of rifts in the volcano. The concentrated hydrogen sulfide and sulfur
