ocean resource placer gold tin titanium

Direct extraction of resources is limited to salt; magnesium; placer gold, tin, titanium, and diamonds; and fresh water. Hence mineral is obtained form ocean water is magnesium.

Placer Gold, Tin, Titanium, and Diamonds. Placer deposits are accumulations of resistant and insoluble minerals that have been eroded from their original locations of formation and deposited along river courses or at the ocean margins. The most important of these deposits contain gold, tin, titanium…

Gold, diamonds, garnet, chromium, tin, iron, and titanium are examples of heavy minerals that may be extracted from beach placer deposits. Nearshore underwater mining, and mining of uplifted marine terraces are important sources of these valuable mineral resources.

Placer tin provides Malaysia and Thailand with about 10% of their exports. The contribution of placers to world mineral production (by weight) ranges from 34% for diamond to 69% for gold. Tin placers yield 49%, while 69% of titanium comes from sedimentary sources.

The major placer materials in the U.S. are tin, titanium, gold, platinum, and chromium. Diamonds are the only gemstone presently mined offshore. World production of diamonds has grown to 100 million carats in the nineties but offshore mining produced less than 100 thousand carats in 1995.

Summary: Placer concentrations of tin, gold, diamonds, amber and other minerals form an important part in the mineral resource potential of the Russian Arctic shelves. These concentrations occur within the nine major zones which include 20 smaller regions differing in the type of placer mine­ rals. Of primary interest are the gold and tin placers.

The continental shelf contains several resources such as oil, phosphorite, manganese, gold, tin, diamonds, and titanium. Deep water deposits are found along mid-ocean ridges where superheated water is released into the ocean. Mineral deposits form producing concentrations of …

These include the chemical precipitation in layers, in the case of most of iron and manganese and some copper deposits, placer deposits of gold, tin, platinum and titanium, and concentration by weathering and groundwater (e.g., of diamond brought to the surface from kimberlite pipes; forming of bauxite and laterite by chemical weathering), and ...

The Ocean Park Placer is a gold mine located in Pacific county, Washington at an elevation of 26 feet. About the MRDS Data: All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy.

gets of gold, tin, platinum, or other valuable min­ erals that have been derived from rocks or veins." Gold in placer deposits is recovered by panning the gold-bearing material, or by using a rocker or a sluice box. In large-scale mining operations, wash­ ing plants and dredges are used. For the purposes of

60 nations. Several placer minerals, in particular titanium, tin, mag-netite, chromite, zircon, monazite, and staurolite are recovered by dredging. Similarly gold, platinum-group metals, and diamonds have been recovered from offshore beach deposits, and large low-grade concentrations still exist which may be mined in the future.

Furthermore, the ocean has been a treasure of placer gold, titanium, tin, and diamonds. These kinds of mineral resources are also formed by the sediments on the shore. The production of sand as mineral resources is also useful for human's life.
