  • Dross - Wikipedia

    Dross is a mass of solid impurities floating on a molten metal or dispersed in the metal, such as in wrought iron. It forms on the surface of low-melting-point metals such as tin, lead, zinc or aluminium or alloys by oxidation of the metal.For higher melting point metals such as steel, oxidized impurities melt and float making them easy to pour off.

  • Aluminum Dross Furnace Salt Slags Processing

  • Aluminium recycling - Wikipedia

    Aluminium recycling is the process by which scrap aluminium can be reused in products after its initial production. The process involves simply re-melting the metal, which is far less expensive and energy-intensive than creating new aluminium through the electrolysis of aluminium oxide (Al 2 O 3), which must first be mined from bauxite ore and then refined using the Bayer process.
