Beach PlacerRelease time：25 February 2020
What is the sea beach placer?
Beach placer deposits are secondary enriched deposits formed by the accumulation of heavy mineral debris in the coastal zone by the action of rivers, waves, tides, and currents. It is mainly composed of rutile, tantalite, magnetite, xenotime, gold, iron, diamond, quartz, coal, and other minerals.
The abundant seabed mineral resources mainly including beach placer and manganese nodules, and seabed hydrothermal ore. Among them, beach placer deposits are widely distributed in coastal areas and continental shelves of coastal countries. There are dozens of proven beach sand minerals in the world, such as gold, platinum, tin, hafnium, titanium, zirconium, and diamond.
More than 40 countries are engaged in the exploration and mining of beach sand. For example, the United States mines ilmenite, zircon ore, and gold placer ore from the seashore; Sri Lanka mines seaside tin ore mines; Australian zircon and rutile production which mined from the seashore placer account for 60% and 90% of the total world output respectively.
What are beach sand minerals?
The main types of minerals are ① metallic mineral, ilmenite, rutile, zircon, magnetite (titanium magnetite); ② rare metal minerals like cassiterite, niobium tantalite; ③ rare-earth minerals like monazite, xenotime; ④ precious metal minerals like placer gold, diamond, silver, platinum; ⑤ non-metallic minerals like quartz sand, shells, amber, etc.
The sea beach sand minerals have great economic value and industry, national defense and high technology application value.
Beach placer deposit distribution in the world
In a general way,
The U.S. Northwest Pacific Ocean —— ilmenite, chromite, and zircon;
Australia and New Zealand —— rutile, zircon, monazite, and ilmenite;
Southwest Africa —— Diamond placer deposit, associated with gold, platinum, chromite, etc.;
South southeast Asia, Indonesia, Thailand, Malaysia —— placer tin deposit;
India, Sri Lanka —— rutile, zircon, monazite, ilmenite, rare metal;
Northwest Pacific coast, especially the Japanese archipelago —— magnetite.
