Publication number: 20240052514Abstract: A method of acid mist suppression in copper electrowinning is described. In various embodiments, at least one liquid licorice root extract, powdered licorice root extract, or reconstituted licorice extract is added in an amount sufficient to the acidic electrolyte solution of the copper electrowinning process to suppress acid mist from the acidic electrolyte solution during the copper electrowinning process. In various embodiments, combinations of licorice extract and surfactant show synergies in acid mist suppression during copper electrowinning.Type: ApplicationFiled: October 23, 2023Publication date: February 15, 2024Applicant: FREEPORT MINERALS CORPORATIONInventors: Scot Philip Sandoval, Stanberg Lee Tallman, William Duane Sanders, Ephrem Lemlem Gebrehiwot, Aron Tyab

Patent number: 8187450Abstract: The present invention relates, generally, to a method and apparatus for electrowinning metals, and more particularly to a method and apparatus for copper electrowinning using the ferrous/ferric anode reaction. In general, the use of a flow-through anode—coupled with an effective electrolyte circulation system—enables the efficient and cost-effective operation of a copper electrowinning system employing the ferrous/ferric anode reaction at a total cell voltage of less than about 1.5 V and at current densities of greater than about 26 Amps per square foot (about 280 A/m2), and reduces acid mist generation. Furthermore, the use of such a system permits the use of low ferrous iron concentrations and optimized electrolyte flow rates as compared to prior art systems while producing high quality, commercially saleable product (i.e., LME Grade A copper cathode or equivalent), which is advantageous.Type: GrantFiled: April 1, 2010Date of Patent: May 29, 2012Assignee: Freeport-McMoran CorporationInventors: Scot Philip Sandoval, Timothy George Robinson, Paul Richard Cook
