Impacts of strip mining: Strip mining destroys landscapes, forests and wildlife habitats at the site of the mine when trees, plants, and topsoil are cleared from the mining area. This in turn leads to soil erosion and destruction of agricultural land. When rain washes the loosened top soil into streams, sediments pollute waterways. This can hurt fish and smother plant life downstream, and ...

As such, the early gold mining economy was reported to be a purely extractive industry with very little consideration for its longterm impacts [7]. For example, as gold mining activity continued along the Rand, mines had to dig deeper — an increasingly expensive exploit — to reach lowergrade gold. During the early years of gold production ...

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. Mining and comminution are highly dependent on the grade of gold ore, as ...
