To study the effects of copper and sulfate ion concentrations on the electrodeposited copper, a series of experiments was conducted at copper ion concentrations of 10 to 50 g/l and at total sulfate ion concentrations of 100 to 250 g/l. Another set of tests was conducted using thiourea grain refining additive concentrations of 0.05 to 8.0 mg/l.

Copper is a valuable metal with many uses. Because of its high demand and versatility, many things that used to be made of solid copper are now being made of other materials and simply plated (or covered) with copper on the outside. This copper plating can be removed by dissolving the copper with specific chemicals, or by grinding it off.
