Combined with Pb isotopic features, we consider that the Erdaokan Ag-Pb-Zn deposit mainly formed from a deep source, with the metals mainly sourced from the magma The Ag, Pb, Zn, Fe, Cu, Mn, S, Sb, Ni, As and Co bearing fluid migrated upward from depth along with the magma at a stable temperature, pressure, salinity and density..
Solder alloys are metallic materials that are used to connect metal workpiec This is achieved by melting the alloy and then cooling it down The choice of specific alloy depends on its melting point, chemical reactivity, mechanical properties, toxicity, and other propertiHence a wide range of solder alloys exist, and only major ones are listed below..
