Mineral economics is the academic discipline that conducts research and education on economic and policy issues associated with the discovery, extraction, processing, use, recycling, and disposal of mineral commodities. As Robinson (1989) shows, its roots can be traced back to the early development of economics as a formal …
Mining has advanced primarily through the use of two strategies: pyrometallurgy and hydrometallurgy. Both have been used successfully to extract …
Special Issue Information. Dear Colleagues, Advances in the mineral processing steps are constant. Crushing develops more efficient particle breaking, avoiding fine particles, and optimizing energy consumption. The liberation step is the grinding process and consumes most of the energy in a mineral processing plant.
