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.
