Coal mining processing plant in Nigeria. This coal mining project is an open pit mine located in Nigeria, announced by mining company - Western Goldfields - that it has discovered 62,400,000 tonnes of proven reserves of coal deposits worth US$1.2 billion which could be used for the generation of electric power...

Abstract The Near Earth Asteroids are primary targets for resources to support space industrialization. Robust technical and economic approaches to project planning feasibility evaluation are needed to evaluate such space mining ventures. This paper discusses the technical engineering and mission-planning choices and shows how the concept of probabilistic Net Present Value can be used to ...
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.
2012-4-25 potential mining and processing methods. The literature also highlights the need for rigorous ways of comparing alternative hypothetical projects and deciding between competing targets, and competing mining, processing, propulsion, and power system choices, which all interact in complex ways.

Future space industrialization will prompt the search for in-space resources, for construction and propellant mass. This thesis reviews the literature regarding space resources, and notes the tremendous expansion in knowledge of the Near-Earth asteroids over the last decade, in regard to their population, compositions, and accessibility, making them primary targets of interest.
