What drives GHG emissions from copper production ...
Nov 24, 2016 · A large open pit copper mine may use in the order of 200,000 L/d of diesel, with an emissions factor of about 2.7 kg CO2 e/L, resulting in 200,000 t CO2 e/y of emissions. That’s typically around 2 – 4 t CO2e/t Cu produced.
Transparency on greenhouse gas emissions from mining to ...
Feb 03, 2020 · Copper mining can serve as a case study to analyse the measurable pathways by which mining contributes to climate change through direct and indirect greenhouse gas emissions.

Apr 22, 2020 · BHP estimates deals announced last year to switch two giant copper mines in Chile to solar, wind and hydro sources in place of existing coal and gas power that will cut energy costs …
Better Planet - Sustainable Copper
Recycling copper saves energy, reduces greenhouse gas emissions, extends the life of natural resources and saves valuable land from being used for landfills. Copper is essential for the renewable energy technologies needed to combat climate change, including solar panels and wind turbines.
Energy and environmental implications of copper production ...
Primary copper production is one of the most important sources of energy-generated CO 2 emissions; in Chile, fuel consumption at plants and at utilities that supply electricity to copper mining is responsible for 21% of the emissions of this gas arising from stationary energy consumers .

Mining for emissions reductions? Strike while the earth is ...
Aug 30, 2018 · Mining companies will play a critical role in the energy transition, providing the raw materials needed to grow these nascent industries. Metals that likely will be needed for the low-carbon transition include copper, silver, aluminum (bauxite), nickel, zinc, neodymium and indium.
Energy and greenhouse gas impacts of mining and mineral ...
Life cycle assessments of the mining and mineral processing of iron ore, bauxite and copper concentrate were carried out, focussing on embodied energy and greenhouse gas emissions. The results showed that loading and hauling make the largest contributions to the total greenhouse gas emissions for the mining and processing of iron ore and bauxite.
Explainer: These six metals are key to a ... - Carbon Brief
Global copper ore quality is declining over time, for example, meaning copper mining requires excavating twice as much ore as 10 years ago to yield the same amount of copper. This means more mine waste and greenhouse gas emissions, although research has shown a shift to other available technologies and more efficient processes could go some way to addressing this impact.
Scientists propose framework to mitigate mining’s impact ...
The researchers estimated that greenhouse gas emissions associated with primary mineral and metal production were equivalent to approximately 10% of the total global energy-related greenhouse gas ...

Lower-pH Copper Flotation Reagent System - Energy.gov
Home» Lower-pH Copper Flotation Reagent System. New Reagent System Improves Recovery, Reducing Energy Use and Air Emissions in the Mining Industry. In the mining industry, flotation is a process that concentrates minerals from their ores prior to metal recovery. Current practice uses slurry pHs in excess of 10, achieved by adding burnt lime (CaO).
Energy and Mining: Challenges Present New Opportunities ...
As the copper resource is developed, mining begins by extracting ore closest to the surface. As these resources are removed, equipment must mine ore from an increasing depth. Deeper pits result in longer, uphill hauls for trucks to deliver ore to the mill for processing — increasing diesel consumption, which results in greater energy consumption and GHG emissions.
Greenhouse gas emissions of copper mining in Chile 2018 ...
Direct greenhouse gas emissions of the copper mining industry in Chile amounted to more than six million metric tons of CO2 in 2018, up from 5.98 million tons a year earlier.
