In-situ Leaching
In-situ Leaching :
Extracting metals or other minerals from ore by allowing an acid-containing liquid to flow through the ground that contains the minerals. The minerals are dissolved by the acid (leached) and captured when the liquid is collected. Leaching is also used to recover minerals from waste rock that contains too low a concentration of the mineral to be worth recovering by typical extraction (mining and processing) methods. Incineration: high temperature combustion of materials in an enclosed device. incinerator ash: ash from the incineration of waste. in growth: in a sample, the buildup of radionuclides that are products of radioactive decay. internal conversion: transmission of the excess energy of the nucleus to one of the orbital electrons; the electron may be ejected from the atom (ionizing radiation)
