The environmental impact of gold production

The LCA assessed production from both non-refractory ores, which are relatively easy to treat, and refractory ores where the gold is 'locked-in' and requires more complex processing. As non-refractory ores become depleted, the ability to recover gold from refractory ores has become more important. For an ore grade (i.e. metal content) of 3.5

Mankind started mining for precious metals between 20,000 and 40,000 years ago. For the last century, mining has been one of our planet's largest industries (it generated 683 billion dollars in revenue in 2018 alone).. This only underscores the fact that our desire for precious metals and minerals has grown exponentially since we first started digging through the topsoil to get at raw and

Environmental Impact Assessment (EIA) of a gold

produced depends on the type of mineral extracted, as well as the size of the mine. Gold and silver are among the most wasteful metals, with more than 99 percent of ore extracted ending up as waste. By contrast, iron mining is less wasteful, with approximately 60 percent of the ore extracted processed as waste (Da Rosa, 1997; Sampat, 2003).

Mining & Extraction | Global Forest Atlas

Mining has always been an environmentally disruptive activity, but contemporary extractive industries are located in some of the most ecologically sensitive forests in the boreal and the tropics. Oil, gas, and mineral extraction account for an estimated 7% of global deforestation in the subtropics, with increasing exploration and development taking place in the Amazon and Congo basins.
