  • Recovery of tin and copper by recycling of printed circuit

    Recovery of tin and copper by recycling of printed circuit boards from obsolete computers L A Castro; The secondary leaching of the 218N H 2 SO 4 + 30N HCl system reached a level of 90% Sn extraction and only 123% Cu extraction from the primary leaching residue The 30N HCl system gave 891% Sn and 332% Cu extraction Based on the experimental results, secondary leaching proved to29/09/2011· Recovery rates for typical finishing operations are approximately 95 percent or higher RO systems have been used to recover chromium, copper, zinc, brass, cadmium, tin, palladium and other precious metals, but the most common application for RO technology is in the recovery of acid nickelRecovery/Recycling Methods for Metal Finishers |01/01/2003· There were also additional reports on recovery of Nb and Ta from tin slag, Au and Ag from tin slag or other slags and so on Unlike iron and steel slags, the application of nonferrous slags may cause environmental concerns since they usually contain a notable amount of heavy metals or even toxic elements with a relatively high solubility ( Manz et al, 1997 , Atzeni et al, 1996 )An overview of recovery of metals from slags

  • Recrystallization (metallurgy) Wikipedia

    Recrystallization is defined as the process in which grains of a crystal structure come in a new structure or new crystal shape A precise definition of recrystallization is difficult to state as the process is strongly related to several other processes, most notably recovery and grain growthIn some cases it is difficult to precisely define the point at which one process begins and another endsTin processing, preparation of the ore for use in various products Tin (Sn) is a relatively soft and ductile metal with a silvery white colour It has a density of 729 grams per cubic centimetre, a low melting point of 23188 °C (44938 °F), and a high boiling point of 2,625 °C (4,757 °F) Tin is allotropic; that is, it takes on more than one formTin processing | BritannicaSecondary copper recovery is attracting increasing interest because of the growth of copper containing waste including ewaste The pyrometallurgical treatment in smelters is widely utilized, but(PDF) Secondary copper processing using Outotec
