Gold Mine Ore Processing and Production: National Emission

2011-2-17  On February 17, 2011, the U.S. Environmental Protection Agency (EPA) promulgated National Emissions Standards for Hazardous Air Pollutants for gold ore processing and production facilities, the seventh largest source of mercury air emission in the United States. EPA estimates that the final rule will reduce mercury emissions by 1,460 pounds per

The environmental impact of gold production

2019-7-25  The stages that contributed the most to gold’s environmental impact were mining and comminution (crushing and grinding of the ore). Electricity use was responsible for just over half of the GHG emissions. This indicates that attempts to lessen the environmental impact of gold production should focus on these two stages.

2003-1-20  Crude assay methods are used to estimate gold recovery and to guide the direction of underground excavation. The ore pulled out of these shafts is then packed in sacks and transported, usually by oxen, to a processing plant. In the processing plant, the first step is to crush the ore in order to reduce the processing time at the mills.

Barrick Gold Corporation Sustainability Environment

82% of our 2020 emissions are Scope 1 emissions, which are direct emissions such as from the burning of fuel at our power plants. Our emissions for 2020 now include full year emissions for the NGM joint venture and the assets of the former Acacia Mining plc. In July 2019, we formed Nevada Gold Mines with Newmont Corporation.
