Frasch process mining Britannica

2 天前  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

Sulfur Mining in Indonesia BORGEN

Miners then break up the sulfur with metal pipes, haul the pieces out of the crater and carry them several miles to the weighing station. Typically, a miner will make several circuits in a day, carrying loads of 100-200 pounds each. The antiquated process of sulfur mining in Indonesia poses extreme health hazards and safety issues for the miners.

For precisely this reason, the mine permitting process often requires corporations to offer financial assurances for potential environmental damages. However, financial assurances underestimate damages,and taxpayers are left with the bulk of sulfur-ore mine cleanup costs for generations.

New process aids sulfur oxidation at Hycroft Mine

2021-1-20  The smaller Brimstone plant can process approximately 5,000 gallons per minute and was built in 2009 and the larger plant on the north side of the mine can process 21,500 gallons per minute and was built between 2012 and 2013. Hycroft’s gold and silver mine is located in the Sulfur Mining district, 54 miles west of Winnemucca.

Chemistry of Sulfur-Contaminated Soil Substrate from

The impact of tree litter on soil chemistry leachate and sulfurous substrates of mine soils from former Jeziórko sulfur mine was investigated. Composites were used: soil substrate (less contaminated at mean 5090 mg kg−1 S or high contaminated at 42,500 mg kg−1 S) + birch or pine litter and control substrate (no litter). The composites were rinsed with distilled water over 12 weeks.
