Acid mine drainage from coal and mineral mining operations is a difficult and costly problem. In the eastern U.S., more than 7,000 kilometers of streams are affected by acid
With rich ore mining, beneficiation and smelting technology and experience, we have completed the design and research of more than 2,000 mines, which can not only provide customers with reasonable process flow, but also provide customized equipment configuration.
ground waters interact with these wastes, acid mine drainage can be created, and this is probably the most serious environmental problem of metal mining and beneficiation. When water interacts in an oxidizing environment with the sulfide minerals typical of most metal mines, sulfuric acid is created.
Oct 03, 2017· PTFE (or Teflon™) – PTFE, also commonly known as Teflon™, is one of the most acid resistant materials available and is commonly used in chemical and pharmaceutical lab applications. Aside from being resistant to many acids used in labs, most people know PTFE (or Polytetrafluoroethylene) as one of the best materials for low friction properties.
高达10%返现· The bacteriumThiobacillus ferrooxidans plays an important role in acid production due to its ability to rapidly oxidize reduced forms of iron and sulphur which can result in the generation of H2SO4. The sulphide mineral pyrite (FeS2), often present in waste materials, is generally recognized as the chief source of acid mine drainage.Cited by: 27
