<p>PURPOSE:To separate easily and inexpesively effective components from an Al alloy material by immersing the material in an alkali soln. to dissolve Al and by carrying out solid-liq. separation. CONSTITUTION:An Al alloy material is immersed in a 0.5-4N aqueous soln. of sodium hydroxide to dissolve Al in the material, and solid-liq. separation is carried out. Effective components such as Sn, Cu, Pb, Si, Cr and Sb can be separated and recovered from the Al alloy material. Zn or the like can not be separated because it is dissolved in the alkali soln.</p> |
