How does hydraulic mining work?

Hydraulic mining is a technique used to extract gold and other minerals from soil and rock by using high-pressure water jets. The process involves directing a powerful stream of water onto the surface of the mining site, which erodes the soil and dislodges the desired materials. The slurry created is then collected and processed to separate the valuable minerals from the sediment. This method was particularly popular during the California Gold Rush but has since faced environmental concerns due to its impact on landscapes and waterways.
