| Підсумок≠ | The Ellingham Diagram, introduced by Harold Ellingham in 1944, is a graphical representation of the Gibbs free energy change for oxide formation and reduction as a function of temperature. It is an essential tool for predicting the thermodynamic feasibility of ore reduction and selecting appropriate reducing agents and temperatures for smelting and roasting operations. | Electrowinning is an electrochemical process that extracts and refines metals from dilute leaching solutions by passing electric current through an electrolytic cell. Metal ions migrate to the cathode (negative electrode) and are reduced to pure metal, while impurities remain in solution. This process is essential for copper, zinc, cobalt, nickel, and gold refining, producing metals of exceptional purity. |
