[emoji3][emoji3][emoji3][emoji3][emoji3]Ipo Lithium ya kumwaga Tanzania. Wakenya ni masikini mno hatutakiwi kuongea nao watatuchelewesha. Wakenya siyo wenzetu, wakenya ni wachuuzi tu.
USES OF LITHIUM
USES OF MANGANESEThe Kibakwe Manganese Occurrence is in Dodoma, Tanzania. Ore mineralization has been found at this location, however the precise grade, tonnage, and extent of the mineralization are not known. There has been no production and little to no activity other than routine claim maintenance since the mineral discovery.
Manganese is too brittle to be of much use as a pure metal. It is mainly used in alloys, such as steel.
Steel contains about 1% manganese, to increase the strength and also improve workability and resistance to wear.
Manganese steel contains about 13% manganese. This is extremely strong and is used for railway tracks, safes, rifle barrels and prison bars.
Drinks cans are made of an alloy of aluminium with 1.5% manganese, to improve resistance to corrosion. With aluminium, antimony and copper it forms highly magnetic alloys.
Manganese(IV) oxide is used as a catalyst, a rubber additive and to decolourise glass that is coloured green by iron impurities. Manganese sulfate is used to make a fungicide. Manganese(II) oxide is a powerful oxidising agent and is used in quantitative analysis. It is also used to make fertilisers and ceramics.
USES OF NEODYMIUMNgualla is one of the world’s largest and highest grade undeveloped neodymium (Nd) & praseodymium (Pr) rare earth projects.
The Ngualla Rare Earth Project is centred on the Ngualla Carbonatite in southern Tanzania, 147 kilometres from the city of Mbeya on the edge of the East African Rift Valley. The name ‘Ngualla’ comes from the Swahili word for ‘bald head’, which reflects the appearance of the hill – mostly bare land on which there is no habitation, agriculture, grazing or reserves.
The most important use for neodymium is in an alloy with iron and boron to make very strong permanent magnets. This discovery, in 1983, made it possible to miniaturise many electronic devices, including mobile phones, microphones, loudspeakers and electronic musical instruments. These magnets are also used in car windscreen wipers and wind turbines.
Neodymium is a component, along with praseodymium, of didymium glass. This is a special glass for goggles used during glass blowing and welding. The element colours glass delicate shades of violet, wine-red and grey. Neodymium is also used in the glass for tanning booths, since it transmits the tanning UV rays but not the heating infrared rays.
Neodymium glass is used to make lasers. These are used as laser pointers, as well as in eye surgery, cosmetic surgery and for the treatment of skin cancers.
Neodymium oxide and nitrate are used as catalysts in polymerisation reactions.

Although China is the main producing nation, gadolinium is also found in countries such as the USA, Brazil, India, Australia, Greenland and Tanzania.
Gadolinium has useful properties in alloys. As little as 1% gadolinium can improve the workability of iron and chromium alloys, and their resistance to high temperatures and oxidation. It is also used in alloys for making magnets, electronic components and data storage disks.
Its compounds are useful in magnetic resonance imaging (MRI), particularly in diagnosing cancerous tumours.
Gadolinium is excellent at absorbing neutrons, and so is used in the core of nuclear reactors.

Na madini yote hayo bado hatujatoka tu shida iko wapNickel ipo kwa wingi Tanzania. Wakenya mtakoma sasa. Mnaweza kusema mbona hivi, mbona vile. Ndiyo tunakuja sasa.

Kuna mkunya eti bila aibu anasema Kenya ni tajiri kuliko Tz, anaongopewa na GDP ushuzi hahahahaaa hajui km GDP ni namba tu zinabadilika mda wwte km tulivyoamua kuibadili.Neodymium ipo nyingi tu ya kumwaga Tanzania. Tunaweza kuanza Electronic devices Manufacturing hapa hapa Tanzania. Tuachane na wakenya waendelee na ukabila wao.

Sikujua kama tuna madini ya aina nyingi hivyo, Kwanini bado uchumi wetu mdogo ilihali tuna mali nyingi namna hiyo ilo ndio swali nilikua najiulizaSijakuelewa.

Mkuu ilo swali linashida gani?Hao waliotuchelesha mbona magereza hazijajaa kwann tusiwape AdhabuSs mkuu haujuwi shida ilikuwa wapi? Huoni mabadiliko na tunapoelekea? Mbn umeuliza swali hili mkuu.
Madini mengi yalikuwa hayajachimbwa kutokana na sababu nyingi mojawapo kukosa ubunifu wa kuvutia wawekezaji lkn pia hata yale ambayo tulikuwa tunachimba viongozi waliingia mikataba ya kibinafsi isiyo na faida kwa taifa, hauoni kwa ss tumeanza kurekebisha sheria na tayari tumeanza kuona matunda yake?Sikujua kama tuna madini ya aina nyingi hivyo, Kwanini bado uchumi wetu mdogo ilihali tuna mali nyingi namna hiyo ilo ndio swali nilikua najiuliza

Yani kuna watu unashindwa kuwaelewa.Ss mkuu haujuwi shida ilikuwa wapi? Huoni mabadiliko na tunapoelekea? Mbn umeuliza swali hili mkuu.
Nimekusoma Apo! !Sababu zipo nyingi sana.
1. Mwalimu Nyerere alijua uwepo ma madini yote hayo. Lakini yasingeweza kutusadia kama tusingekuwa imara kisiasa.
2. Alitaka watanzania wapate elimu kwanza ndipo waweze kuchimba madini hayo.
3. Tanzania miaka ya 80s iliwekewa vikwazo tukawa tumejikita katika uzalishaji wa chakula cha kututosha.
4. Tulianza kuchimba madini kipindi cha awamu ya tatu. Mikataba mibovu iliingiwa.
Kwahiyo sasa hivi tupo na utashi na uelewa tunajua thamani ya madini hayo. Ndio maana imetungwa sheria ya madini kwa lengo la kuinufaisha Tanzania.
