Copper is a good conductor because, like other metals, it contains free electrons. Free electrons are also known as conduction electrons. Each copper atom provides a single free electron, so there are as many free electrons as atoms. (See Figure 1). Free electron concentration in copper, n = 8.5 × 10 28 per m 3
In copper electrowinning, the effects of temperature, power outages and concentrations of cobalt and manganese on anode corrosion and current efficiency have not been well investigated. Benchscale tests were used to investigate these effects. Anode corrosion in all experiments was minimal probably due to the presence of at least 150 mg/L
