Mine drainage refers to any surface water or groundwater that drains from an active or abandoned mining operation. Mine drainage can be high-quality similar to natural waters or contaminated by leftover materials. Polluted mine drainage can be extremely acidic and is often laden with high concentrations of toxic, heavy metals.

Surface mining – Surface mining methods are designed for extracting ore from surface deposits. The largest mines are normally surface mines. Heavy machinery and blasting procedures are used to remove large quantities of surface rock, which considerably disturbs the land. A typical surface mine can produce up to 150,000 tons …
