how to remove dross from rotary furnace

  • Lead Dross, Lead Melting Equipment, Lead Melting Technology

    With tin and Lead the dross can also be removed by adding sodium hydroxide pellets, which dissolve the oxides and form a slag. Dross is distinguished from slag, which is a (viscous) liquid floating on the alloy, by being solid. Lead Dross shall consist of slag, dross, skimming or spilling from Lead melting operations. A scum formed on the surface of molten metal.

  • Removing the Dross from the Silver

    Jul 07, 2013Verse 4 spoke about removing the dross. Merriam Webster defines DROSS as: "1-the scum that forms on the surface of molten metal; 2- waste or foreign matter : impurity; 3- something that is base, trivial, or inferior." Once the dross is removed from the silver, what remains is beautiful and is what the silversmith works with for his design.
