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.

DEVELOPMENT OF ALUMINUM DROSS-BASED MATERIAL .

1.1 Definition of Dross and General Scope of Related Aluminum Recycling Aluminum Dross is a by-product of Aluminum production. Today much energy is consumed to recover the Al from the dross; energy could be saved if the dross diverted and utilized as an was engineering material. There are two forms of dross –white dross and black dross.

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.

Slag and/or Dross Formation Tendency - themetalcasting

Aluminum oxide dross layer, which forms a layer on the top of molten metal, can be removed from the molten metal through drossing fluxes. Dross and metal (in liquid or solid form) are usually blended together in this layer of dross. When drossing fluxes react on aluminum oxide in slag or dross layer, metal can usually be separated and recovered.

Zinc solder dross containing 14.8% Sn, 16.3% Pb, 0.41% Al and 64.5% Zn was leached with 3% H 2 SO 4 at 45°C for 1 h. Zinc and aluminum went into solution, whereas lead and tin remained with the residue. Aluminum was selectively precipitated as calcium aluminum carbonate by treating the sulphate leachate with limestone at pH 4.8.
