Recycling Energy Use Similarity A brief comparison to energy consumption of large size objects in recycling is made here to place mining energy consumption in context. In 2010 two thirds of the steel produced in the U.S. was manufactured using ferrous scrap not mined ore [19]. Also the level of steel recycling reported in the US was at 84%, nearly all the material supply chain needs for steel

Energy. Both crushing and grinding require energy to reduce the ore size. However, in grinding operations we consume much more eneregy than crushing, up to 100 times ( thousands of kw compared to tens in crushing). Because as far as we go to finer size we need more force and collosions for further size reduction.
