Foundation Damage Due to Composition or Inclusions - InspectAPedia

Examining how pyrite and sulfites in shale can cause building problems may give added insight to how fragments of these materials may cause trouble when mixed right into concrete as aggregate. Shale formations in at least 20 U.S. states containing various clay and iron sulfide minerals (pyrite) react to water and form mild sulfuric acid causing ...

Copper Ore-SBM Industrial Technology Group

Usually, the beneficiation process is simple. Firstly, ore is ground until the material whose size is around 200mesh takes up 50%~ 70%. Next, the material would undergo coarse separation once, careful separation twice or three times and scavenging once or twice. If the copper ore is fine, phased grinding and separation process is adopted.

How to Remove Pyrite from Coal - Metallurgist & Mineral Processing Engineer

The source of nearly 50 pct of the sulfur content of an average bituminous coal used by an electric utility is pyrite (FeS2); pyrite is a component that is not chemically bound to the coal and, therefore, can be removed by physical separation methods. Removing 50 to 70 pct of the pyrite would accomplish only a 25- to 35-pct reduction in SO2 ...

Pyrite in Aggregate| Concrete Construction Magazine

Pyrite in Aggregate. By Concrete Construction Staff. Is the presence of pyrite in an aggregate likely to be injurious to concrete? The presence of an appreciable amount of pyrite (iron disulphide) is undesirable, since this compound readily decomposes into weak products such as iron sulphate and limonite, along with the formation of sulfuric acid.
