  • Hydrometallurgical process for recovery of metals and/or semimetals from waste materials containing compound semiconductor materials and/or back contact materials and/or transparent electrically conducting oxides (TCOS)
    Patent number: 10060010
    Abstract: A hydrometallurgical process for recovery of metals and/or semimetals from waste materials, such as high-tech or green-tech wastes, and/or electrical and electronic waste containing compound semiconductor materials and/or back contact materials and/or transparent electrically conducting oxides (TCOs), wherein the waste materials according to the invention are mixed thoroughly with a reaction solution of water, 1 to 5% by mass sodium bisulphate and 1-5% by mass sodium chlorite or with a reaction solution of water, 1 to 50% by mass organosulphonic acid and in the stoichiometric ratio to the organosulphonic acid 1-5% by mass of an oxidizing agent, and the metals and/or semimetals that are to be recovered are dissolved.
    Type: Grant
    Filed: February 25, 2014
    Date of Patent: August 28, 2018
    Inventors: Ulrich Loser, Wolfram Palitzsch
  • Method for concentrating metals from scrap containing metal
    Patent number: 10041142
    Abstract: The invention relates to a method for concentrating metals, in particular silver and/or tin and/or lead from scrap containing metal, by treating the material/scrap containing silver and/or tin and/or lead with a sulfonic acid of the formula R—SO2—OH in the presence of an oxidizing agent, wherein R can be an organic group or ammonia.
