Asteroid mining

Mining operations require special equipment to handle the extraction and processing of ore in outer space. The machinery will need to be anchored to the body, [citation needed] but once in place, the ore can be moved about more readily due to the lack of gravity. However, no techniques for refining ore in zero gravity currently exist.

mining - mining - Surface mining: It has been estimated that more than two-thirds of the world''s yearly mineral production is extracted by surface mining. There are several types of surface mining, but the three most common are open-pit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, the techniques used, and the minerals produced.
