The environmental impact of gold production

2019-7-25  The stages that contributed the most to gold’s environmental impact were mining and comminution (crushing and grinding of the ore). Electricity use was responsible for just over half of the GHG emissions. This indicates that attempts to lessen the environmental impact of gold production should focus on these two stages.

Gold Ore - an overview ScienceDirect Topics

Impure gold anodes are dissolved anodically in hydrochloric acid electrolyte, and 99.99% pure gold is deposited at the cathode. Gold of at least 99.5% purity is required for the anodes, because too much silver results in silver chloride built up on the surface, preventing dissolution.

Mineral Resources: Formation, Mining, Environmental

Surface mines include open-pit mines, which commonly involve large holes that extract relatively low-grade metallic ore (see Figure Open Pit Mine), strip mines, which extract horizontal layers of ore or rock, and placer mines, where gold or diamonds are extracted from river and beach sediment by scooping up (dredging) the sediment and then separating the ore by density. Large, open-pit mines can create huge piles of rock (called overburden) that was removed to expose the ore

How digital innovation can improve mining

A gold mine was under severe pressure because the gold grade of the ore body it was mining had fallen by around 20 percent. The mine had increased ore-production volumes to try to offset the decline, but it was running into difficulties because this was overloading its leaching plant and incurring higher costs on energy, chemicals, and other major input costs.
