The ore minerals in most of the world's iron and manganese reserves were chemically precipitated in the ocean and accumulated on the sea floor. Placer deposits are heavy metallic minerals, such as iron or titanium minerals, or native gold or diamonds, that have been concentrated by wave or water action in a river or beach environment. The source of the minerals may be far upstream and contain very low .
Placer Deposits A placer deposit is a concentration of a natural material that has accumulated in unconsolidated sediments of a stream bed, beach, or residual deposit. Gold derived by weathering or other process from lode deposits is likely to accumulate in placer deposits because of its weight and resistance to corrosion.
Technically a placer deposit is the general term for a mineral deposit formed by the concentration of moving particles by gravity. Alluvial is the name for placer .

Placer mining is frequently used for precious metal deposits (particularly gold) and gemstones, both of which are often found in alluvial deposits—deposits of sand and gravel in modern or ancient stream beds, or occasionally glacial deposits. The metal or gemstones, having been moved by stream flow from an original source such as a vein, are typically only a minuscule portion of the total deposit.
Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments. Insitu mining, which is primarily used in mining uranium, involves dissolving the mineral resource in place then...

Even fool's gold (copperiron pyrites) give you one more gold tracer clue to help you find where gold is. That tracer is often concentrated with gold in placer deposits. Oftentimes you see iron, magnetite (black cubes), lead and pyrite in goldbearing placers. This is because it's a heavier than average mineral containing iron and sulfides ...
a placer deposit consists of some valuable mineral that accumulates in weathered rock or overburden in stream sediments or in beach deposits as aresult of natural weathering and erosion processes.
