A quarry is a type of openpit mine that produces rocks and minerals that are used to make buildings. Figure : This diamond mine is more than 700 meters deep. Placers are valuable minerals that have collected in stream gravels, either modern rivers or ancient riverbeds.

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of % pure copper called cathodes, which will ultimately be made into products for everyday use.

'Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by largescale earth disturbances characteristic of mining and other large construction activities, usually within rocks containing an abundance of sulfide minerals.

The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.

For the last 5,000 years or more, tribes across the central region of North America have traveled to this site to quarry. Today, they still travel long distances to this site to continue the tradition of pipestone quarrying and pipe making.
