  • The environmental impact of gold production

    2019-7-25 · For an ore grade (i.e. metal content) of 3.5 gram per tonne of ore, the study estimated that production of each tonne of gold from non-refractory ore used approximately 200,000 gigajoules (GJ) of energy and 260,000 tonnes of water. It produced 18,000 tonnes of GHGs (CO 2 equivalent) and 1,270,000 tonnes of waste solids.Iron and Steel Analysis IEA,Demand for steel, which drives steel production, is a key determinant of energy demand and steel subsector CO 2 emissions. Global crude steel production increased by 5% in 2018 to reach 1 817 Mt, following 6% growth in 2017. Initial estimates suggest 3% growth in 2019. This follows a period of relatively flat demand from 2013-2016.
