Hydraulic mining revolutionized gold mining by allowing large quantities of earth and gravel to be processed quickly and efficiently. This method involved directing water through a nozzle to wash away the gravel and expose the gold-bearing material. The resulting mixture of water and sediment, known as slurry, was then directed into sluice boxes or troughs where the heavier gold particles settled. Hydraulic mining had a significant impact on the environment, causing extensive erosion and sedimentation in rivers and streams. It also led to the destruction of forests and habitats, as large areas were cleared to access the gold deposits.

Cyanide Leaching

Cyanide leaching is a widely used method in gold mining for extracting gold from low-grade ores. It involves the use of a weak cyanide solution that reacts with the gold particles, forming a soluble compound that can be easily separated from the ore. This method is particularly effective for extracting gold from large-scale mining operations. However, it is important to note that cyanide leaching can have significant environmental impacts.

Environmental Impact of Gold Mining
