Mining is essential to meet rising global demand for minerals. Geoscientists locate mineral resources and figure out how to extract them economically while minimizing health and environmental impacts. The method of mining, as well as potential environmental impacts, depends on the type of resource being mined.
The mining process is used to separate rock or ore from surrounding rock. There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. The method used depends on the type of mineral resource that is mined, its location beneath the surface, and whether the resource is worth enough money to justify extracting it. The potential environmental impacts of mining depend on the resource being mined, how it is mined, and local factors like climate. In the United States, these impacts are now closely regulated, and mine areas are often reclaimed for another purpose after mining is over. Read more
