A Guide to Gold Recycling: Sources, Methods, and Benefits
To get enough gold for one ring, miners generate about 50 tons of ore. Mining can also harm the environment, causing air pollution and soil erosion and releasing harmful substances like cyanide. Recycled gold from other sources is a much more sustainable option. Around 25% of the world's gold is recycled! Methods for Recycling …

Open-pit mining. Open-pit mining is the activity of removing the earth to access the mineral deposits and continuing to do it vertically in an open-pit. This method is best suited for mineral deposits that are close to the surface of the earth but are not accumulated in a horizontal manner. Open-pit mining often impacts a narrower surface area.
