Tanzania to become eighth largest Uranium producer in the world

Kwa mtizamo chanya tu hii ni Neema kwangu, Mto Mkuju Mungu asingeshindwa kuuweka China au Urusi(Rassia), Kwa makusudi mazima akautupia Tanzania. Ninaliona jua jipya ambalo halikuwahi kuchwa, likiamka kwa Tanzania na Afrika nzima. Mungu anawatia maadui zetu njaa na kiu, huku ilihali akitujaza na neema ya chakula na maji ili tu kuwafanya adui zetu mateka.
 
Watanzania wengi tunaonesha kukata tamaa lakini naomba mjue tunanguvu kubwa sana endapo tuta amua kuungana na kulikomboa taifa letu,,,mimi niko tayari kulipigania taifa langu mda wowote wewe je?hatustahili kuwa hapa tulipo
 
Hivi mapato ya hiyo Uranium hayawezi kupelekwa vyuo vikuu wadogo zetu wakasoma bure kama sisi? au hazitoshi wachangie japo kidogo?
 
Daily 2nazidi panda kwenye link ya vyanzo vya uchumi na siyo uchumi wenyewe,kweli hii kazi!!
 
We live in tanganyika as if we are refugees.Most of the natural resources in our beloved have become properties of the foreigners under the umbrella of privatisation.This is an unacceptable, let's stand up with our two feet to fight for our riches
 
Hazards of Uranium Mining and Milling.
By Dr. Anne Shirinian-Orlando
Armenian News Network / Groong 2/5/2007
In recent years, there has been an interest in Armenia's uranium
deposits, as displayed by outside entities, such as the government of
Russia, which, just a few days ago, signed an agreement with the RA
government to explore, mine and perhaps also mill uranium in Armenia.
Although it is not clear to the public how much uranium exists in
Armenia (Soviet geologists had estimated deposits to be low, compared
to Central Asian deposits), nevertheless, there seems to be an active
interest in mining uranium in Armenia. The Greens Union of Armenia are
opposed to mining of uranium in Armenia. Given Armenia's small size
and its aging Nuclear Power Station, the carcinogenic and mutagenic
risks and other radiation hazards involved with uranium mining and
milling overwhelm the benefits.
Hazards of Uranium Mining
Waste rock is produced during open pit mining when overburden is
removed, and also during underground mining when driving tunnels
through non-ore zones. Piles of so-called waste rock often contain
elevated concentrations of radioisotopes compared to normal rock.
Other waste piles consist of ore with too low a grade for
processing. All these piles threaten people and the environment due to
their release of radon gas and seepage water containing radioactive
and toxic materials. In addition, to keep water out of the mine during
operation, large amounts of contaminated water are pumped out and
released to rivers and lakes. When the pumps are shut down after
closure of the mine, there is a risk of groundwater contamination from
the rising water level.
Miners are exposed to mine dust and mine radon gas via 3 main
pathways:
- Inhalation/swallowing of radium (an alpha-emitter with a half life
of 1,600 years, a decay product of uranium), also inhalation of radon
gas and of radon progeny.
- External radiation (gamma radiation from uranium ore, alpha
radiation from radon gas, etc.).
- Inhalation of uranium ore dust
For example, Radium is absorbed by the intestine and is carried to
the bone, where it can cause leukemia or bone cancer. Also, uranium
itself is acutely radioactive and toxic.
Past and current health records of uranium miners and of populations
living near the mines and mills show that the radiation in the mines
and from the mill tailings produces an epidemic of cancer both for the
miners and for the population living near the mines and mill tailings
- in particular - throat, lung, liver and bone cancers, as well as
leukemia.
For example: `Cancer cases among Aboriginal people living near
Australia's biggest uranium mine appear to be almost double the
expected rate, a study by the Federal Government's leading indigenous
research body shows' (Sydney Morning Herald, 23 November, 2006).
Another example: `Of the 1,500 Navajo men recruited in the 1940s
through the 1960s from a simple farming life to mine uranium at Cove
and Red Valley, Arizona, 1,112 miners or their families have filed for
government compensation related to lung cancer and other radiation
induced diseases' (Nuclear Madness, by Helen Caldicott). Also, note
that mines have frequent spills, leaks and breaches of regulations, so
that miners can end-up drinking uranium-contaminated water, such as in
the Jabiluka mine, Australia. And finally, consider the legacy of
uranium mining: `Over a decade after uranium mining ended in
Tajikistan, the country is finally facing up to its nuclear
legacy. Specialists estimate that almost 55 million tonnes of uranium
waste lie buried across the north of the country, posing a major
ecological threat. The waste could remain harmful for hundreds of
years. Making it safe would require the kind of technology Tajikistan
just does not possess.' (International War & Peace Reporting (IWPR,
London), Reporting Central Asia Bulletin No.394, July 2005).
Hazards of Uranium Mill Tailings
Ore mined in open pit or underground mines is crushed and leached in a
uranium mill. A uranium mill is a chemical plant designed to extract
uranium from ore. In most cases, sulfuric acid is used as the
leaching agent, but alkaline leaching is also used. The leaching agent
not only extracts uranium from the ore, but also several other
constituents like molybdenum, vanadium, selenium, iron, lead and
arsenic, thus, the uranium must be separated out of the leaching
solution. The final product produced from the mill, commonly referred
to as "yellow cake" (U3O8 with impurities), is packed and shipped in
casks. In the end, large amounts of radioactively contaminated scrap,
that is tailings, are produced, which have to be disposed of. Uranium
mill tailings are normally disposed of (dumped) as a sludge in special
ponds or piles, where they are abandoned. The amount of sludge
produced is nearly the same as that of the ore milled. At a typical
grade of 0.1% uranium, 99.9% of the material is left over as
scrap/tailings.
Apart from the portion of the uranium removed, the sludge contains all
the constituents of the ore. Because long lived decay products such as
thorium-230 (gamma emitter with a half-life of 80,000 years) and
radium-226 are not removed, the sludge contains 85% of the initial
radioactivity of the ore. Radionuclides contained in uranium tailings
emit 20 to 100 times as much gamma-radiation as natural background
levels on deposit surfaces. The radium-226 in tailings continuously
decays to the radioactive gas radon-222, the decay products of which
can cause lung cancer upon inhalation. Some of this radon escapes from
the interior of the pile. Radon releases are a major hazard that
continues after uranium mines are shut down. Since radon spreads
quickly with the wind, many people receive small additional radiation
doses. Also, uranium mill tailings disposed of as sludge in piles or
ponds are anything but safe. For example, `Killer landslides could
spread radioactive pollution across much of southern Kyrgyzstan.
Environmental officials in Kyrgyzstan are warning that a spate of
landslides threatens to contaminate large parts of the Fergana valley
with radioactive waste. Landslides caused by rains occur annually. But
the downpours have been unusually heavy this year, and the mudslides
they create are made worse by the deforestation of mountain slopes
that has taken place over the last decade. Analysts now fear that
toxic waste dumped 30 years ago at a disused uranium mine near the
town of Mayluu-Suu could be washed away in a torrent of mud.'
(International War & Peace Reporting (IWPR), 05 May 2003).
Due to technical limitations, all of the uranium present in the ore
cannot be extracted. Therefore, the sludge also contains 5% to 10% of
the uranium initially present in the ore.
In addition, the sludge contains heavy metals and other contaminants
such as arsenic, as well as chemical reagents used during the milling
process. Moreover, the constituents inside the tailings pile are in a
geochemical dis-equilibrium that results in various reactions causing
additional hazards to the environment. For example, in dry areas,
salts containing contaminants can migrate to the surface of the pile,
where they are subject to erosion. If the ore contains the mineral
pyrite (FeS2), then sulfuric acid forms inside the deposit when
accessed by precipitation and oxygen. This acid causes a continuous
automatic leaching of contaminants, including the radioisotopes.
After hundreds of thousands of years, the radioactivity of the
tailings and thus its radon emanation will have decreased so that it
is only limited by the residual uranium contents.
Conclusion
The issue of uranium mining and milling should be discussed in the
National Assembly. The people must be given the opportunity to decide
for themselves whether to mine or not to mine uranium, since it is the
inhabitants of the mining region, Syunik particularly, and not the
Ministers of the RA government, who will be paying the high cost of
mining. It is the inhabitants of the mining region who will be
deprived of a healthy living space and a sustainable livelihood from
agricultural activity, which will be destroyed as a result of mining.
Thus, the will of the people must be considered in the decision making
process.

Mungu wangu mimi kama mwana mazingira article hii imekuja muda muafaka natafuta lugha rahisi ili kuweka minofu kwenye hii article hila watanzania tutalia na kusaga meno pindi huu uchimbaji utakapoanza kwani uenda sisi tusipate madhara tajwa hapo juu bali wajukuu zetu watatulaani milele kwa madhara watakayo yapata. Shame on you politician ambao mnaenda kutetea uchimbaji wa Uranium UNESCO huku mkiwa mamumma wa athali za uchimbaji mkisukumwa na tamaa zenu za kifisadi ila 2015 sio mbali we will recall those contracts LIWALO NA LIWE kwani sasa hamshauriki tunamwomba Mungu atulinde kwa muda huu ambapo mnanufaika na CAKE yenu. SEE U AT THE POLL 2015.

Dar es Salaam - The first part of the uranium production will start in the second quarter of 2014 as the producer said all production in the first phase will be for the exportation rather than for local use.

Sources from Mantra Tanzania Limited said Tanzanian have nothing to worry as the first batch of the whole production of the uranium mining under Mkuju River Project (MRP) will be for the foreign market first.

"The MPR is shaping up as a truly world-class project and has the potential, in its first phase of its development, to position Tanzania as the third largest producer of Uranium in Africa," the source said.

The government has guaranteed compliance to safety measures at all stages of uranium mining activities following approval by the UN World Heritage Committee to change the borders of Selous Game Reserve where Uranium is found.

Speaking to East African Business Week in Dar es Salaam last week, Minister for Natural Resources and Tourism, Amb Khamis Kagasheki said the country has nothing to worry about, in connection with the acclaimed hazards of uranium as application of modern technology would assure safety to the environment and lives.

"The area set aside for the project is hardly 0.8% of the total area (about 200 square kilometers). The Selous Game Reserves covers a total area of 54,600 sq. km (21,100 sq ml) and has additional buffer zones," Kagasheki said.

The definitive feasibility study, completed in May 2011, indicated that, once developed, the mine will produce 1,990 tonnes of uranium oxide a year and will immediately overtake the USA which produces 1,560 tonnes according to 2009 estimates.

The construction of the MRP planned to commence on the third quarter of 2012, with a 21 month construction period envisaged. It will be the first major mining development within South Eastern Tanzania, bringing jobs and prosperity to a currently under-developed region.

"This will make the country the eighth largest producer in the world," the Mantra official said and added, at this level of production Tanzania will produce three times more uranium oxide than South Africa."

Tanzania is expecting an average annual production of 4.2 million pounds (1,900 tonnes) with the potential to expand production further in a second phase.

The project will have an initial mine life of 12 years, but with a very strong potential to increase this period significantly, the Mantra statement said and it added that, exploration at the Mkuju River Project site is continuing as the deposit has only been explored for less than four years.

The life of a mine, average operating cost of $22.04 per pound, which makes this a low cost producer, as the capital cost including all associated infrastructure was $390 million (Tsh 670 billion).

Several measures which have been taken so as to avoid the effects of the Uranium mining process are together with provision of education to people who are near by the project area, the Mantra said.

Mkuju River Project estimated to create 1,200 jobs during the construction and 600 permanent jobs created during steady state production.
 
hata tungekuwa wa kwanza haina tija wala manufaa kwetu..mbona TZ ndo nchi pekee inayotoa madini ya tanzanitw lakini ni malolosa tupu
 
Pamoja na kwamba hiyo uranium watakaofaidika ni mafisadi wachache, wananchi walio wengi katika maeneo ya karibu wajiandae na side effects zake!! Hizi ndizo side effects za Uranium:

Bila institutions zilizo komaa haya madini yatakua janga kuliko baraka.
Ufisadi umetawala, na tusipo angalia na vita itafata. ona Congo jirani
 
Hujaona 'Tanzanians have nothing to worry about...'
Meaning tutachukua kama wachawi kimya kimya na kusepa.

How much does it take kutengeneza mfumo endelevu wa kuhakikisha tunanufaika? Ggghhhrrrrr!
