Types of land disposed residuals from selected metal smelting and refining industries are described, as are the origin and disposition of land disposed residuals from the primary copper industry as an example. Quantities of land-disposed or stored residuals, including slags, sludges, and dusts, are given per unit of metal production for most primary and secondary metal smelting and refining ind...

It is well documented that slag-based silicon fertilizers have beneficial effects on the growth and disease resistance of rice. However, their effects vary greatly with sources of slag and are closely related to availability of silicon (Si) in these materials. To date, few researches have been done to compare the differences in plant performance and disease resistance between different slag-bas...

The distribution behavior of trace metals between copper matte and spinel-saturated iron silicate slags was investigated at 1250 °C pSO2 0.25 atm low silica concentrations. experiments were conducted in magnetite (Fe3O4) spinel crucibles controlled CO-CO2-SO2-Ar gas mixtures using a high-temperature equilibration-quenching technique. concentrations elements matte, spinel, slag quantified by ele...

The late prehistoric copper production site of the Vilabouly Complex in central Laos delivered different types materials that seem to be related chaine oppératoire for two main sites, Puen Baolo and Thong Na Nguak: minerals, slags crucible fragments. A selection these artefacts were analyzed (OM, SEM–EDS, XRD, bulk analyses) study extraction techniques, raw used steps at Vilabouly. various anal...
