  • Locations of Deposits

    Placer deposits form when minerals are separated by density as lighter minerals remain suspended and more dense minerals are deposited along the riverbed. Bedrock and beach sand deposits constitute the locations of the largest mines. REE-rich minerals are generally found in either carbonatites or peralkaline granites and associated pegmatites.Mining : What is Mining? What are the 4 mining methods,Placer mining is used in river channels, beach sands, or other environments to sift valuable metals from sediments.
