  • Recovery of copper from heap leach residues
    Patent number: 11618934
    Abstract: A process for recovering copper from heap leach residues containing residual copper, includes identifying a production zone within the heap leach residues for secondary leaching, drilling wells into the heap at locations suitable for delivering leach solution into the production zone, injecting the leach solution including ferric ions through the wells and aerating the production zone to facilitate oxidative reactions within the production zone, and collecting effluent from the heap for copper recovery therefrom.

  • Flux and process for hot dip galvanization
    Patent number: 7811389
    Abstract: A flux for use in a hot dip galvanization process has an acidic component so that the flux has a pH of about 1.5 or less. The flux also includes an alkali metal chloride and a nonionic surfactant containing polyoxyethylenated straight-chain alcohols with a hydrophile-lipophile balance (HLB) of less than 11. Depending on the particular application, the flux also includes other components, such as ferric chloride, an inhibitor containing an amino derivative and bismuth oxide.
