2021-11-26 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.
Read More2020-4-1 During digestion process, the S 2 O 3 2− reacts with Fe to corrode equipment, it is extremely dangerous in Bayer process. When the sulfur content of bauxite is over 0.5%, the equipment (such as sleeve pipe preheater, flow pipes, and valves etc.) can be corroded seriously after one month. So the S 2 O 3 2− must be removed in the production ...

Read MoreThe coal sample from the Shijiazhai mine located in the east of Yunnan province of China, is characterized with high ash and sulfur content which are 64.90% and 8.66% respectively. Analysis results indicate that coal and pyrite are the valuable minerals that can be recycled from the crude ore. According to the properties of the ore, a full-flotation flowsheet is proposed to process the ore.
