Copper futures settled lower on Tuesday, hurt by demand concerns following disappointing Chinese data. Data showed that China's industrial production growth slowed to 3.7% in July. Chinese real estate investments declined for the 17th month in a row in July, while home sales dropped as well amid a growing debt crisis. Moreover, firm American currency also dampened copper prices.
