Answer 1

Mining is the extraction (removal) of minerals and metals from earth. Manganese, tantalum, cassiterite, copper, tin, nickel, bauxite (aluminum ore), iron ore, gold, silver, and diamonds are just some examples of what is mined.

Why mine?

Mining is a money making business. Not only do mining companies prosper, but governments also make money from revenues. Workers also receive income and benefits.

Large scale mining versus small scale mining:

• Large scale mining usually involves a company with many employees. The company mines at one or two large sites and usually stays until the mineral or metal is completely excavated. An example of a large scale mine is the Serra Pelada mine in Brazil which yielded 29,000 tons of gold from 1980 to 1986 and employed 50,000 workers (Kricher, 1997).
• Small scale mining usually involves a small group of nomadic men. They travel together and look for sites which they think will yield gold or another valuable metal or mineral. Small scale mining occurs in places such as Suriname, Guyana, Central Africa, and many other places around the world. Some researchers believe that small scale mining is more harmful to the environment and causes more social problems than large scale mining. This will become apparent later in the lesson.
