Jun 21, 2017Silver is the main metal in e-waste recycling. If you have silver in metal form then you can easily melt this. But if you have silver in powder form like silver chloride then you can face many problems in melting silver. As usually, silver melts at 961 C and this temperature point is less than gold melting but melting silver is hard and technical.

Feb 11, 2021Salts containing Cl -, Br -, or I - are generally soluble. Important exceptions to this rule are halide salts of Ag+, Pb2+, and (Hg2)2+. Thus, AgCl, PbBr2, and Hg2Cl2 are insoluble. Most silver salts are insoluble. AgNO3 and Ag(C2H3O2) are common soluble salts of silver; virtually all others are insoluble. Most sulfate salts are soluble.
