The Actual Difference Between Surface and Underground

Surface mining is commonly used to extract coal and copper, and increasingly, precious metals like gold. Underground mining is used for gold, platinum, zinc, lead, and increasingly, coal. As can be seen, surface mining is much more advantageous than its counterpart.

Lead and Zinc - Energy

Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist. The use of underground or surface mining techniques depends on the proximity of the ore body

Zinc Geoscience Australia

The main zinc mineral is sphalerite ( (Zn,Fe)S), which contains up to 67% zinc by mass. Smithsonite (ZnCO3, 52%), willemite (Zn2SiO4, 59%) and hemimorphite (Zn4Si2O7 (OH)2 H2O, 54%) may occur in the near-surface weathered or oxidised zone of an orebody. In some cases, these secondary minerals are also zinc ores.

Surface mining - Wikipedia

Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels. Surface mining began in the mid-16th century and is practiced throughout the world, although the majority of surface coal mining

How can metal mining impact the environment?

Underground mining generally results in relatively small waste rock disposal areas ranging from a few acres in size to tens of acres (0.1 km2). These areas are typically located near the openings of the underground workings. Open pit mining disturbs larger areas than underground mining, and thus has larger visual and physical impacts.
