iron mining effect

It is primarily from waste in the mining of sulphide ores that serious environmental problems can arise due to their content of iron sulphides such as pyrite and pyrrhotite. When mining waste containing iron sulphides is allowed to lie unsheltered and comes under the effects of weather and wind, it will crumble through an oxidation process.

Mining Waste Treatment Technology

Reactive mine wastes can be isolated from oxidizing agents (i.e., O 2, Fe 3+) by chemically precipitating a ferric coating on the surface of the waste material. This passivation process, sometimes called "microencapsulation," prevents further oxidation of sulfide minerals by blocking the transport of oxidants to the sulfide surface and consuming ferric iron before it can become an oxidant.
