Which commodity mining does NOT have byproducts?Court Jester said:it is infact 70% of ALL silver production around the globe is a byproduct of mining another primary metal. e.g. Zinc, Leah, Gold
That piece of ground known as "ore" usually contains a variety of elements, and usually they don't let it pass to the wastebin because the additional cost to extract another element is usually much smaller than the cost of the primary. Because same equipment can be used.
About the factor "energy", let's look at crude oil: http://finviz.com/futures_charts.ashx?t=QA&p=w1
Or heating oil. Or natural gas. The price seriously dropped during 2014, back to the level it was before the crisis.
Just to say, even the "measurement" involved variables can change the cost picture in a serious way.
