what is the cost of mining and or processing of iron

Mining Industry Information - Mine Engineer.Com

Copper mining costs are being reported ranging from around $2/pound to a high of $3.20 per pound. As China's economy cools to a 5% growth rate, they require fewer resources, such as steel and copper, so the demand weakens, but if American and European economies ever recover, copper will again rise to the $4 per pound level.
