Reason: This is a common problem mining ball mills face, resulting in low productivity and low ore processing efficiency. One reason may be the improper design of the grinding chamber, which affects the flow of materials and reduces grinding efficiency. Additionally, worn or damaged liners can hinder the grinding process by reducing the effective impact …

Any material that contains the mineral pyrite (FeS 2), or some other iron sulphide mineral, has the potential to produce acidity in the surrounding surface environment.That's because pyrite oxidizes quite readily at surface, and its oxidation leads to the release of hydrogen ions (H +) into the surface water and groundwater.A simplified equation for this process is as …
