Life cycle inventory analysis of the production of metals

2009-4-1  Solid wastes in mining comprise the biggest solid waste contributor in the life cycle of the metals. In addition to the ore itself, a large amount of waste rock (overburden) is removed to get access to the ore, especially in surface mines. The ratio of overburden to concentrator mill tailings in the US is now about 1.9:1 .
