The seaside sand ore refers to the secondary enrichment mining bed formed by the coastal area by rivers, waves, tide, and sea flow, and the heavy mineral debris gathers. It includes both sand mines that are currently in the seaside area, and formed on the seaside during the geological period. Later, sand mines that are below the sea due to rising sea surface or decline in the coast. There are abundant solid minerals buried below the sea and bottom, mainly including coastal sand ore and manganese tuberculosis, and underwater heat liquid mine. Among them, the coastal sand mines are widely distributed in the coastal area and continental shelf of coastal countries. There are dozens of kinds of coastal sand ores that have been proven in the world, mainly including gold, platinum, tin, tin, titanium, titanium, tadpoles, diamonds and other metals. Now more than 30 countries are engaged in the exploration and mining of sand mines. For example, the United States mining titanium iron ore, vermiculite ore, golden sand mines, etc.; Sri Lanka mining seaside tin sand mines, Indonesia and Thai tin sand ore mining water depth of more than 40 meters; 60%and 90%of the world's total output; 13 types of sand mines in my country's industrial mining value, mainly titanium iron ore, vermiculite, vermiculite, and gold red stone. These seaside sand mines are generally high. The content of titanium iron ore is 3%to 4%; the content of vermiculite essence is 23%to 65%; the percentage content of gold and redstone is 24%to 67%; It reaches 20%to 22%; the average content of magnetite is 6.3%to 7%, and the ore iron content is 13%to 56%; the tin stone contains 0.2 to 1 kg of tin per cubic meter, and some are 10%. Each cubic meter contains 0.31 to 3.68 carats (1 carat is 200 mg); the content of gravel per ton of gold ore is 5.2 to 50 grams.
The seaside sand ore is mainly distributed in the coastal continental shelf area. The main minerals are: titanium iron ore, gold red stone, vermiculite, and magnetite (titanium magnetite) in metal minerals; Mine; lone stone and phosphorus ore in rare earth minerals; sand gold, diamond, silver, platinum in precious metal minerals; quartz sand, shells, amber, etc. in non -metal minerals. The economic value of Binhai Sand Mine has obvious economic value, and has major application value in industrial, defense and high -tech. The submarine phosphorus ore refers to a phosphorus -containing material that is enriched on the bottom and has obvious industrial value through biological deposition or biochemical deposition. Its main mineral component is phosphorus. It is mainly distributed in the coastal Bund, shallow sea racks and other places, and the depth of output is generally tens of meters to hundreds of meters. Underwater phosphorus ore is widely used in medicine, food, matches, dyes, sugar, ceramics, national defense and other industrial fields. Mepatal tuberculosis and cobalt -rich manganese shell. Multi -metal tuberculosis contains dozens of elements such as manganese, iron, nickel, cobalt, and copper. Departed group blocks. There are more on the sea plains with 4500-5500m in water depth. The richest in the Pacific, followed by the Indian Ocean and Atlantic Ocean. The combustible ice is a new type of mineral called natural gas hydration. Under low temperature and high pressure conditions, ice -state solid substances composed of hydrocarbons and water molecules. Its energy density, small impurities, almost no pollution after burning, thick layer, large scale, and wide distribution. With the gradual maturity of mining technology, the widespread application of combustible ice in the future will bring new hope to human development.
