Copper for July delivery jumped 21 cents to $3.3145 a pound Friday. It was the biggest one-day jump since Oct. 24, 2011.
The price of copper tends to rise when investors expect the economy to strengthen. Copper has a wide range of industrial uses in making electronics and construction materials, and demand for the metal increases when manufacturing and homebuilding accelerate.
Other metals were little changed.

Crop futures ended mixed.
