Where Does Placer Gold Come From? Part 3 Placer West Coast Placer
Placer Deposits Form When. Placer deposits form when heavy eroded particles settle out of moving water. The placer can be an accumulation of valuable minerals formed by gravity separation during sedimentary processes.

Web placer mining ( / ˈplæsər /) [1] is the mining of stream bed ( alluvial) deposits for minerals. Placers can be found in rivers (alluvial placers) and on the coast, particularly in beaches. Web placer deposit, natural concentration of heavy minerals caused by the effect of gravity on moving particles. Typically, placers form where a stream’s velocity slows on point bars, in braided streams, or in alluvial fans (figure 9.92). Placer mining is frequently used for precious metal deposits (particularly gold) and gemstones, both of which are. Web placer deposits result from weathering and release of gold from lode deposits, transportation of the gold, and concentration of the gold dominantly in stream gravels. The word placer is spanish for alluvial sand. Web “placer” deposits are formed by surface weathering and ocean, river or wind action resulting in concentration of some valuable heavy resistant minerals of economic quantities. The name is from the spanish word placer , meaning alluvial sand. The placer can be an accumulation of valuable minerals formed by gravity separation during sedimentary processes.
Mineral deposits formed as a result of gravity separation based on density are called placer deposits. Typically, placers form where a stream’s velocity slows on point bars, in braided streams, or in alluvial fans (figure 9.92). Web placer mining ( / ˈplæsər /) [1] is the mining of stream bed ( alluvial) deposits for minerals. Web mineral found in placer deposits. Placer deposits form when heavy eroded particles settle out of moving water. Web “placer” deposits are formed by surface weathering and ocean, river or wind action resulting in concentration of some valuable heavy resistant minerals of economic quantities. The word placer is spanish for alluvial sand. Web placer deposit, natural concentration of heavy minerals caused by the effect of gravity on moving particles. Web so, placer deposits, also just called placers, form when one or more minerals concentrate in this way to become an ore deposit. Placers can be found in rivers (alluvial placers) and on the coast, particularly in beaches. Placer mining is frequently used for precious metal deposits (particularly gold) and gemstones, both of which are.
