“…For fossil resources, future technology development is accounted for in the estimates made by the International Energy Agency (2013). For mineral resources, technological innovation, economies of scale and new discoveries may partly offset higher costs of extracting resources (Crowson 2012;Curry et al 2014). Reserves beyond 20-30 years of consumption are rarely identified (Yaksic and Tilton 2009), meaning that new mining projects with lower costs than other running mines in the future may occur.…”

“…As higher grade ore bodies are exhausted, the average grades of the remaining deposits will diminish requiring even greater volumes of ore to be milled to meet the growing demand (Crowson, 2012;Mudd et al, 2013;Northey et al, 2014;Prior et al, 2012). It is also well established that comminution is the most energy intensive stage of mineral processing and that the process is inherently inefficient (Batterham, 2011;BCS, 2007;Curry et al, 2014;Nadolski et al, 2014;Tromans, 2008). Furthermore, new ore bodies are often more complex, occurring in harder rock with finer grain sizes, which further increases the energy required to liberate the valuable minerals for downstream separation processes (Cooke et al, 2006;Norgate and Jahanshahi, 2011;Sillitoe, 2010).…”

“…According to the literature, haulage costs can be some of the largest in a mining system [133,134]. In various case studies it was found that material transportation represents 50 per cent of the operating costs of a surface mine [135].…”
