Placer Deposits
Placer deposit or placer is a natural accumulation of heavy valuable minerals which are formed by the gravitational effect during sedimentary processes. Placer mining is critical for gold extraction and one of the main mining methods used in several gold rushes including the California Gold Rush.
PHASES OF A MINING PROJECT
Placer mining Placer mining is used when the metal of interest is associated with sediment in a stream bed or floodplain. Bulldozers, dredges, or hydraulic jets of water (a process called 'hydraulic mining') are used to extract the ore. Placer mining is usually aimed at removing gold from stream sediments and floodplains. Because placer mining often occurs within a streambed, it is ...

What Is Placer Mining? (with picture)
Placer mining is a group of mining methods that use water to separate valuable minerals or ores from the surrounding sediment. It can be used to recover platinum, tin, and diamonds, but most commonly gold. A very crude form of placer mining was used by gold prospectors during the California gold rush in the mid 1800s. Since then, the technology has progressed to allow a larger volume of ...
