- Hydraulic Mining
- A mining method that uses high-pressure jets of water to wash away dirt or gravel containing precious minerals.
- This method is mainly used for gold mining. The unconsolidated river beach sand is washed into the ditch, where the gold is separated from other minerals because of its specific gravity.
- Hydraulic mining is banned by law in many mining areas, as large amounts of crushed rock are poured into rivers to pollute river water, hamper navigation and damage nearby crops.
