The name is from the Spanish word placer, meaning "alluvial sand". Placer mining is an important source of gold, and was the main technique used in the early years of many gold rushes, including the California Gold Rush.
In the early period of mining REEs, they were mined primarily from placer deposits, which are mineral accumulations in rivers and on beaches.

But solutions can also form deposits by dissolving and removing valueless material, leaving a residuum of less-soluble ore minerals. Deposits developed as residues from dissolution are called residual deposits.
In some beach and river-bar placers where the mining practice is to “skim” the rich streak, magnetite often amounts to several percent of the material washed.
