environmental impacts of gravel gold ore

The environmental impact of gold production

2019-7-25  However, gold is produced in much smaller quantities, so the total environmental footprint for global gold production is smaller than some other commonly used metals, including steel, copper and aluminium. The stages that contributed the most to gold’s environmental impact were mining and comminution (crushing and grinding of the ore).

Environmental Issues in Gemstone Mining — Gemstones

Environmental impacts of mining largely depend on the methods used and the geological context that governs how easily the minerals can be separated from the ore material. Unlike gold mining, which often uses potentially toxic chemicals such as mercury and cyanide, gemstone mining does not depend on chemicals for extraction of the rough material.
