Table of ContentsMaterials and MethodsResults and Discussion Effect of Particle Size on the Flotation Effect of Particle Size at a 100mesh GrindSummary and Conclusions Desulfurization of coal before combustion is becoming important for the effective utilization of this major energy resource without polluting the environment.
Sep 28, 2015· Pyrite has a significant effect on the spontaneous combustion of coal. The presence of pyrite can change the propensity of coal towards spontaneous combustion. The influences of various pyrite contents on the parameters of spontaneous combustion, such as index gases, temperature and released heat etc., were investigated in this study.
Acid Mine Drainage: Chemistry Acid mine drainage impacts stream and river ecosystems through acidity, ferric ion (Fe 3+) precipitation, oxygen depletion, and release of heavy metals associated with coal and metal mining, such as aluminum (Al 3+), zinc (Zn 2+), and manganese (Mn 2+).. When mineral deposits that contain sulfides are mined, they have the potential to produce acid mine drainage.

The effects of mining coal on the environment. There are 2 ways to mine coal – Strip Mining and Underground Mining – both ways have their own impact to the environment and health. We know it but coal is such a cheap energy source that we don''t want to let go of it. The negative effects of coal mining cannot be disputed:
Pyrite has a significant effect on the spontaneous combustion of coal. The presence of pyrite can change the propensity of coal towards spontaneous combustion.
In natural settings this is seldom a concern, but pyriterich waste from mining operations can significantly increase the acidity of surface waters. This increased acidity can harm downstream ecosystems and may even pose a serious risk for human populations. Many coal deposits contain disseminated pyrite and as the coal is burned the pyrite''s ...
