Bauxite mining, which is considered as surface mining, is land extensive, noisy and dusty. Mining pits are often interspersed with small rural communities, thereby requiring companies relocate the people andor to monetarily compensate them. An increasing concern is the loss of habitat for Jamaicas unique plant and animal species.

Giant shovels then scoop up the bauxite-rich soil and dump it into trucks, which carry the ore to a processing plant. France was the first site of large-scale bauxite mining. In the United States, Arkansas was a major supplier of bauxite before, during and after World War II.
Although some bauxite deposits are hard rock, most consist of relatively soft dirt that is easily dug from open-pit mines. Australia produces more than one-third of the worlds supply of bauxite. It takes about 4 lb 2 kg of bauxite to produce 1 lb 0.5 kg of aluminum metal.
This has caused mining costs to become a more important factor than location near a smelter. Environmental Issues caused by bauxite mining. Due to the methods of mining open cast, the end result of mining on the landscape is very unsightly. Jamaican regulations ensure that the land is reclaimed when mining in an area is complete.
