Environmental impact of high-value gold scrap recycling,

25-08-2020· The gold routes satisfying the global gold supply are mining (74%), recycling of high-value gold (23%), and electronic scraps (3%). Besides its applications in the investment, jewelry, and industrial sector, gold also has a bad image. The gold production in industrial as well as artisanal and small-scale mines creates negative impacts such as resource depletion, extensive chemical use, toxic,Environmental impact of high-value gold scrap recycling,Environmental impact of high-value gold scrap recycling Benjamin Fritz1 & Carin Aichele1 & Mario Schmidt1,2 Received: 31 March 2020/Accepted: 12 August 2020 # The Author(s) 2020,only half a gram per ton of ore, for example, in the artisanal and small-scale mining (ASM) in Brazil to several tens ofEnvironmental Net Benefit of Gold Recycling,of recycled gold mainly occur in the operations of the recycling facility. Recycled gold has a lower environmental impact in all impact categories with the exception of global warming potential. High electricity use in the gold recycling process is responsible for 81% of the global warming impact.

The environmental impact of gold production

This indicates that attempts to lessen the environmental impact of gold production should focus on these two stages. Mining and comminution are highly dependent on the grade of gold ore, as the lower the grade, the greater the amount that needs to be mined and the more crushing and grinding is required to extract the gold from the ore.(PDF) Recycling of gold from electronics: Cost-effective,,Recycling of gold from electronics,which is backed up by other studies that have examined the impact of,The main problems with the formalisation of knowledge in the gold ore refinement,Environmental Impact Assessment (EIA) of a gold mine,,Gold mine tailings dams are a high risk part of mining as they contain hazardous materials such as cyanide, mercury and arsenic from processing operations which present a risk to the public and to the environment. When tailing dams fail, the impact is disastrous for humans and the natural environment.
