Avoided energy cost of producing minerals: The case

2019/11/1One of these factors is the difficulty of extracting metals from ores (cost of extraction), . Another factor is speculation related to the physical reality of the commodities. According to historical data regarding commodity prices from the USGS [29], the price of iron ore was lowest in 1901 (1.71 US$/t) and highest in 2012 with (116.48 US$/t).Get price
