Electrolytic cell Wikipedia
An electrolytic cell uses electrical energy to drive a nonspontaneous redox reaction An electrolytic cell is a kind of electrochemical cellIt is often used to decompose chemical compounds, in a process called electrolysis—the Greek word lysis means to break upImportant examples of electrolysis are the decomposition of water into hydrogen and oxygen, and bauxite into aluminium and other Finally, the goldbearing solution is ready for electrowinning, which recovers the gold from the leaching chemicals In electrowinning, operators pour the goldbearing solution into a special container known as a cell Positive and negative terminals in the cell deliver a strong electric current to the solution This causes gold to collect on Extracting Gold HowStuffWorksA Mathematical Model of a Zinc Electrowinning Cell AC SCOTT, RM PITBLADO and GW BARTON University of Sydney, NS W, Australia A detailed fundamental model of a zinc electrowinning cell has been developed and validated for both steady state and dynamic simulations This model wasA Mathematical Model of a Zinc Electrowinning Cell
