The Technical and Economic Feasibility of Mining the Near

There have been various concepts proposed for mining and retrieval to low-earth-orbit of materials from NEAs, but methods of comparison of the economic feasibility of competing mission concepts are not well-developed. In-situ production at the asteroid of the propellant needed for materials return is an important “enabling” concept.

A Beginners Guide to PEA's and Feasibility Studies

Aug 05, 2020 Before a project becomes a mine, several technical studies must be completed in order to determine the viability of the project. The first of these is the preliminary economic assessment (PEA), with pre-feasibility (PFS) and feasibility studies (FS) that follow. All of these studies analyze and assess the same geological, engineering and economic factors; however, they include significantly

Copper Mining and Processing: Life Cycle of a Mine Superfund

Surface mining, which includes strip mining, open-pit mining, and mountaintop removal, removes soil and rock from on top of the mineral deposit. It may begin as soon as the pre-development steps are complete. Underground mining uses shafts and tunnels to access deeply-buried mineral deposits, while the overlying rock is left in place.
