    Vast deposits of rare earth minerals, crucial in making high-tech electronics products, have been found on the floor of the Pacific Ocean and can be readily extracted, Japanese scientists said on Monday.

    The estimated rare earths contained in the deposits amounted to 80 to 100 billion metric tons, compared to global reserves currently confirmed by the U.S. Geological Survey of just 110 million tonnes that have been found mainly in China, Russia and other former Soviet countries, and the United States.

    A chronic shortage of rare earths, vital for making a range of high-technology electronics, magnets and batteries, has encouraged mining projects for them in recent years.

    China, which accounts for 97 percent of global rare earth supplies, has been tightening trade in the strategic metals, sparking an explosion in prices.

    Japan, which accounts for a third of global demand, has been stung badly, and has been looking to diversify its supply sources, particularly of heavy rare earths such as dysprosium used in magnets.

    The sea mud was especially rich in heavier rare earths such as gadolinium, lutetium, terbium and dysprosium.
    "These are used to manufacture flat-screen TVs, LED (light-emitting diode) valves, and hybrid cars," he said.

    Extracting the deposits requires pumping up material from the ocean floor. "Sea mud can be brought up to ships and we can extract rare earths right there using simple acid leaching," he said.

    "Using diluted acid, the process is fast, and within a few hours we can extract 80-90 percent of rare earths from the mud."

    I rushed to read your thread thinking the discovery was in Tanzania. Japan!

    yanaweza kuwepo, lakini sidhani kamakuna report yoyote ama research yoyote ambayo imeshafanyika

    Let's say we are rich in RARE EARTH METALS, then what? Ili waje watuchimbie na kutuachia kiduchu kama kwenye GOLD - ok haba na haba hujaza kibaba, lakini hicho kibaba mafisadi wanakausha siku mbili tu. Sasa licha ya bidhaa za viwandani, China wametajirika kwa kupitia rare metals na mafuta kwa kuwa wanachimba wenyewe.

    Tz tuna wasomi wa madini toka miaka na miaka, lakini ukweli unabaki pale pale kua kama NCHI bado hatupo serious. China juzi tu walikua kama sisi, wenzetu mambo mengine wanajifunza kutenda hata kabla ya kuyasomea - very priactical indeed.

    ... Mkuu, hayo yote unayo-point out ni kweli. A lot of us are well aware of the ongoing insatiable looting of our riches which are after all, our right, legally and otherwise. That our land is well endowed with all sorts of mineral riches is factual. What has happened to gold could also happen to the mining of other precious metals. It is quite a laugh that we appear to have been duped into using USD 260 base for the price of one ounce of gold and letting the same remaining fixed. Current price exceed USD 1000. There loss of revenue is collosal.

    I did a research on this article and they said they find those minerals in Tanzania, Wigu Hills... Read the Article
    Tanzania we are blessed

    Despite the obvious need for more rare earth mines around the world there are in fact very few known projects. Mining database, Intierra, lists only around 200 rare earth mine projects, of which only about 20 are at an advanced stage with some kind of resource listed. The majority of these advanced stage deposits are in Canada, Greenland, USA (including plans to restart Mountain Pass), parts of southern Africa (RSA, Tanzania, Malawi) and Australia. There are just four advanced rare earth projects in Australia (though there are some by-product rare earth projects) including Navigator Resources' Cummins Range; and the Mount Weld, Nolan's Bore and Yangibana projects.
