    Kuna Mwanajamii aliweka hapa kuhusu Rare Minerals yamepatikana Japan; lakini tumecheki online na tumeona kuwa Tanzania is one of the rare countries ie. China, Japan, USA, Australia, SA with capabilities and found in WIGU HILLS

    The rare earth metals include the fifteen lanthanide metals (which appear as part of the fold out section at the bottom of the periodic table) and two other metals - scandium and yttrium, which occur with the lanthanides geologically and have very similar properties. The fifteen lanthanides are lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium and lutetium. Of the fifteen lanthanides, all occur naturally apart from promethium, which is an element that has to be artificially produced in laboratories.

    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.

    If there are sufficient so called rare metals for mining profitably, pm me with details, I have the investors.

    .. Thank you Mkuu, nguu007. It is imperative to raise awareness against possible plunder being perpetrated against our utajiri while we are dancing KIDUKU and sinking further into destitution. The same could be said about PLATINUM.

    hivi vitu huwa tunaishia kuvisoma tu, matatizo yapo pale pale hayana faida yoyote kwa mtanzania

    Yeah, Waandishi wetu wengi wa habari wanaandika habari za Siasa kuliko utajiri wa Nchi Yetu na Kinachoendelea kupatikana hapa nchini

    [h=2]Tanzania now battles China`s monopoly on rare earth metals

    China has over 95 percent market share in the global production of rare earth metals, but many alternatives are now being examined, such as the Wigu Hill deposit in Tanzania owned by Montero Mining.[/h]



    Apparently Wigu Hill has a lot going for it, both geologically and geographically, according to a US newspaper San Franscisco Chronicle of last week. Wigu is located 200km west of Dar es Salaam.
    Montero president and CEO Tony Harwood argues that Wigu Hill's first competitive advantage is its simple carbon material, unlike many rare earths which are found in deposits that are complicated by radioactive materials or silica, creating all kinds of processing, and cost, issues.
    "Geologically because the deposit is carbonatite in form with no associated radioactive materials present such as uranium or thorium that while potentially adding a revenue stream also greatly complicate the handling, concentrating and refining processes," the paper quoted him as saying.
    He says that concentration is another facet of the geological advantages in Wigu's favor, saying it goes as high as 25 per cent, but is likely to average between 7 and 10 per cent. The newspaper says the other advantage is Tanzania's geographic proximity to world class mining, processing and refining expertise in neighboring South Africa.
    "Opportunities like this in Tanzania should be a reminder that there are actually rare earth deposits all over the world," the paper says.
    Actually, production in places like North America was shut down in the past due to environmental concerns plus cost competitiveness from China, it says, adding that South Africa and India used to be the world's leading producers.
    Now that rare earths demand is surging due to their use in battery technology, old production areas can be re-started and new ones can be discovered, it says.
    Wigu is of even higher grade than China's huge Bayan Obo mine that produces most of the world's supply: While China might have a monopoly in the near-term, since it takes time to re-start old rare earth mining activities in other places, in the long-term there is actually no shortage of 'rare earths', the paper concludes.
    Rare earths are a collection of seventeen chemical elements in the periodic table, Scandium and Yttrium, and the 15 lanthanides of Lanthanum, Cerium, Praseodymium, Neodymium, Promethium, Samarium, Europium, Gadolinium, Terbium, Dysprosium, Holmium, Erbium, Thulium, Ytterbium and Lutetium.
    According to scientists, rare-earth metals are the key to 21st Century technology: Without them, we wouldn't have smartphones, hybrid cars or precision weapons.

    ... haya bana! I bet kwamba ukifanyika deep investigative journalism, kininja, kwa maana ya kuwa armed to the teeth, unaweza gundua maajabu ya plunder. Katika sample space yangu, seti ya factors kadhaa zitajirudia na significance ya measure, probability in this sense inaweza angukia pazuri sana. This might sound a bit whacko of me, nikiri kwamba I am not out to impress if at all hiyo nayo ni significant. Nategemea aje MDAU mwenzetu hapa aandike, yote hayo ya measures hayahitajiki, kwani its obvious. Modus operandi ya mijizi na washirika wao ile ile siku zote. Ila huku kwetu wamekwaa lulu. Nipo nje kidogo ya Dar, na niseme iko joto ile mbaya. I wish plae ofisini kwetu tungeweza transplant miti ya ku-filter UV-R angalau tupumue kidogo. Issue being we can afford mitambo kibao ya kuzalisha umeme in surplus save for subversion activities za RA and cohorts. I remain maaad as the surplus of sunshine outside.

    hiyo milima kumbe iko karibu na hifadhi ya mikumi, wakati niko shule niliwahi sikia kuwa kila kwenye mbuga za wanyama,hifadhi za taifa,magereza na kambi za jeshi huwa kuna vitu vya thamani sana e.g gold,mafuta,uranium etc, juzi tu ndani ya Selous game reserve kumetangazwa kuna uranium,sasa nimecheki tena na huu mlima wenye rare earth minerals upo ndani/karibu ya mikumi.
