Terrace mining is the term used to describe a mining method where the gem bearing rocks are exposed by digging horizontal terraces in step-like, generally circular formations. Blasting or digging is done and the debris is then washed to obtain the gem gravels. Emerald mining in Columbia (Chivor Mine) is the best example of terrace mining.

Mining is the process of digging into the earth to extract naturally occurring minerals. It can be categorized as. surface mining, underground mining, and in situ mining. Surface mining is used to excavate ores at or close to the earth's surface ; underground and in situ mining both remove minerals from deeper deposits.

In the United States, the first copper mine was opened in Branby, Connecticut, in 1705, followed by one in Lancaster, Pennsylvania, in 1732. Despite this early production, most copper used in the United States was imported from Chile until 1844, when mining of large deposits of high-grade copper ore around Lake Superior began.

The mining industry in the early Middle Ages was mainly focused on the extraction of copper and iron. Other precious metals were also used mainly for gilding or coinage. Initially, many metals were obtained through open-pit mining, and ore was primarily extracted from shallow depths, rather than though the digging of deep mine shafts.
