electrowinning cell

Electrolysis | Definition, Uses, & Facts | Britannica

electrolysis, process by which electric current is passed through a substance to effect a chemical change. The chemical change is one in which the substance loses or gains an electron (oxidation or reduction). The process is carried out in an electrolytic cell, an apparatus consisting of positive and negative electrodes held apart and dipped into a solution containing …

A galvanic cell (voltaic cell) produces a flow of electrons. This flow of electrons is called an electric current. Current is given the symbol I and is measured in units of amperes (amps, A). The amount of charge passing a point in an electric circuit depends on the electric current and the time the current is allowed to flow for.
