Web mineral found in placer deposits. 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. Web so, placer deposits, also just called placers, form when one or more minerals concentrate in this way to become an ore deposit. Web placer deposit, natural concentration of heavy minerals caused by the effect of gravity on moving particles. Web in geology, a placer deposit or placer is an accumulation of valuable minerals formed by gravity separation from a specific source rock during sedimentary processes. Placers can be found in rivers (alluvial placers) and on the coast, particularly in beaches. The placer can be an accumulation of valuable minerals formed by gravity separation during sedimentary processes. 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. Web placer mining ( / ˈplæsər /) [1] is the mining of stream bed ( alluvial) deposits for minerals. The name is from the spanish word placer , meaning alluvial sand.
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. When heavy, stable minerals are freed from their matrix by weathering processes, they are slowly washed downslope into. Unless preserved by burial, a placer subsequently may be eroded, and either dispersed or reconcentrated. Minerals that form placer deposits include precious deposits like gold, platinum, copper, zircon and various gemstones apart from magnetite, ilmenite, chromite, cassiterite, rutile, and native monazite. Web placer deposit, natural concentration of heavy minerals caused by the effect of gravity on moving particles. Placer mining is frequently used for precious metal deposits (particularly gold) and gemstones, both of which are. The name is from the spanish word placer , meaning alluvial sand. Web in geology, a placer deposit or placer is an accumulation of valuable minerals formed by gravity separation from a specific source rock during sedimentary processes. Heavy eroded particles settle out of moving water. The word placer is spanish for alluvial sand.
