How can metal mining impact the environment? American

Tailings produced from the milling of sulfide ores — primarily copper, lead, and zinc ores — may have concentrations of pyrite that are greater than those common in waste rock. Also, because tailings are composed of small mineral particles the size of fine sand and smaller, they can react with air and water more readily than waste rocks.

Environmental Risks of Mining

Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.

Ore Wikipedia

An ore is a natural occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted at a profit from the earth through mining they are then refined (often via smelting) to extract the valuable element, or elements.

:: WorstPolluted : Projects Reports

Lead is almost always contained in sulfide ores as galena, or lead sulfide 45. Waste rock material from mines that contain metal sulfides can lead to sulfuric acid drainage when left out in the open air. Tailings also contain minerals and materials that can lead to dangerous runoff and water contamination when stored improperly.
