    Abstract: A sorting system for aluminum scrap using laser-induced breakdown spectroscopy (LIBS) has been developed, which employs the sequential sample cells that are moved by the electric actuator in order to carry scrap pieces. A combination of a Q-switched Nd: YAG laser (30mJ, 10ns) with an objective lens having a long focal length of 600 mm were used to ... Show More

    Abstract: At early stages of the formation of planetary bodies, silicate, metallic, and sulfide phases, which have been formed in the course of the partial or complete fusion of the initial planetary substance, were subject to a gravitational differentiation. The latter is related to the separation of the crystalline and molten phases in density and composit... Show More
