Environmental Impacts of Gold Mining
Solid Waste . Digging up ore displaces huge piles of earth and rock. Processing the ore to produce metals generates immense quantities of additional waste, as the amount of recoverable metal is a small fraction of the total ore mass.In fact, the manufacture of an average gold ring generates more than 20 tons of waste.. Heap Leaching
Sustainable and responsible development of minerals
Often there are trade-offs between different environmental objectives. Open pit mining, for example, has lower energy requirements than underground mining, generally leading to lower emissions, but it results in more land use change. However, there are also cases where an alternative presents synergistic outcomes.
