Kwanza hangaikeni na huu ushuzi kabla ya dar kuwatoa kamasi 🤣🤣👇👇Huu mji ulijengwa na wajerumani kabla mburura wa kiingereza kuhamishia makao makuu kwenye kijiji cha Dar es salaam
Makao mkuu ya wajerumani yalikuwa Bagamoyo, na baadae kuhamishiwa Dar es salaam. Waingereza hawakuwa na mamlaka yoyote ya kuhamisha makao makuu kwasababu Tanganyika haikuwa koloni lao.Huu mji ulijengwa na wajerumani kabla mburura wa kiingereza kuhamishia makao makuu kwenye kijiji cha Dar es salaam

Tanzanian iron ore reserves are located mainly in Liganga, Uluguru Mountains, Mbabala near Lake Tanganyika, Karema, Manyoro Gondite and Itewe.
Wakenya ni maskini wa kutupwa hatutakiwi hata kuongea nao.About 80% of the vanadium produced is used as a steel additive. Vanadium-steel alloys are very tough and are used for armour plate, axles, tools, piston rods and crankshafts. Less than 1% of vanadium, and as little chromium, makes steel shock resistant and vibration resistant. Vanadium alloys are used in nuclear reactors because of vanadium’s low neutron-absorbing properties.
Vanadium(V) oxide is used as a pigment for ceramics and glass, as a catalyst and in producing superconducting magnets.
Helium is used as a cooling medium for the Large Hadron Collider (LHC), and the superconducting magnets in MRI scanners and NMR spectrometers. It is also used to keep satellite instruments cool and was used to cool the liquid oxygen and hydrogen that powered the Apollo space vehicles.
Because of its low density helium is often used to fill decorative balloons, weather balloons and airships. Hydrogen was once used to fill balloons but it is dangerously reactive.
Because it is very unreactive, helium is used to provide an inert protective atmosphere for making fibre optics and semiconductors, and for arc welding. Helium is also used to detect leaks, such as in car air-conditioning systems, and because it diffuses quickly it is used to inflate car airbags after impact.
A mixture of 80% helium and 20% oxygen is used as an artificial atmosphere for deep-sea divers and others working under pressurised conditions.
Helium-neon gas lasers are used to scan barcodes in supermarket checkouts. A new use for helium is a helium-ion microscope that gives better image resolution than a scanning electron microscope.
Uranium is a very important element because it provides us with nuclear fuel used to generate electricity in nuclear power stations. It is also the major material from which other synthetic transuranium elements are made.
Naturally occurring uranium consists of 99% uranium-238 and 1% uranium-235. Uranium-235 is the only naturally occurring fissionable fuel (a fuel that can sustain a chain reaction). Uranium fuel used in nuclear reactors is enriched with uranium-235. The chain reaction is carefully controlled using neutron-absorbing materials. The heat generated by the fuel is used to create steam to turn turbines and generate electrical power.
In a breeder reactor uranium-238 captures neutrons and undergoes negative beta decay to become plutonium-239. This synthetic, fissionable element can also sustain a chain reaction.
Uranium is also used by the military to power nuclear submarines and in nuclear weapons.
Depleted uranium is uranium that has much less uranium-235 than natural uranium. It is considerably less radioactive than natural uranium. It is a dense metal that can be used as ballast for ships and counterweights for aircraft. It is also used in ammunition and armour

Nickel resists corrosion and is used to plate other metals to protect them. It is, however, mainly used in making alloys such as stainless steel. Nichrome is an alloy of nickel and chromium with small amounts of silicon, manganese and iron. It resists corrosion, even when red hot, so is used in toasters and electric ovens. A copper-nickel alloy is commonly used in desalination plants, which convert seawater into fresh water. Nickel steel is used for armour plating. Other alloys of nickel are used in boat propeller shafts and turbine blades.
Nickel is used in batteries, including rechargeable nickel-cadmium batteries and nickel-metal hydride batteries used in hybrid vehicles.
Nickel has a long history of being used in coins. The US five-cent piece (known as a ‘nickel’) is 25% nickel and 75% copper.
Finely divided nickel is used as a catalyst for hydrogenating vegetable oils. Adding nickel to glass gives it a green colour
The known rich areas in phosphate deposits lies to the Southwestern Tanzania along the Panda Hills, about 25 kilometres from Mbeya township to the South of Tanzania having a reserves of about 370 million tonnes of phosphate with Serengeti plains being said to have huge phosphate carbonate. The Nguella Carbonate in Chunya district to the south of Tanzania is also is another area with huge phosphate deposits with Nachendezwaya in Ileje Mbeya near Songwe river being said to have 5.1 million tonnes deposits of phosphate.
Tanzania to map its phosphate deposits - East African Business Week
MWANZA, Tanzania– The Ministry of Energy and Minerals is going to map Tanzania’s phosphate deposits. According to the Minister, Prof Sospeter Muhongo, a directive concerning the exercise has already been issued to the ministry’s mineral experts. Once complete, it would allow the Tanzania State...www.busiweek.com
BIOLOGICAL ROLEWhite phosphorus is used in flares and incendiary devices. Red phosphorus is in the material stuck on the side of matchboxes, used to strike safety matches against to light them.
By far the largest use of phosphorus compounds is for fertilisers. Ammonium phosphate is made from phosphate ores. The ores are first converted into phosphoric acids before being made into ammonium phosphate.
Phosphorus is also important in the production of steel. Phosphates are ingredients in some detergents, but are beginning to be phased out in some countries. This is because they can lead to high phosphate levels in natural water supplies causing unwanted algae to grow. Phosphates are also used in the production of special glasses and fine chinaware.
Phosphorus is essential to all living things. It forms the sugar-phosphate backbone of DNA and RNA. It is important for energy transfer in cells as part of ATP (adenosine triphosphate), and is found in many other biologically important molecules. We take in about 1 gram of phosphate a day, and store about 750 grams in our bodies, since our bones and teeth are mainly calcium phosphate. Over-use of phosphates from fertilisers and detergents can cause them to pollute rivers and lakes causing algae to grow rapidly. The algae block out light stopping further photosynthesis. Oxygen dissolved in the water soon gets used up and the lake dies
USES OF LITHIUMLiontown Resources (ASX:LTR) has identified high-grade, spodumene-related lithium mineralisation at its Mohanga Lithium-Tantalum Project in Tanzania.
The Mohanga Project, which Liontown acquired in late 2015, covers a total area of 177 square kilometres and is located circa 40 kilometres from Tanzania’s capital Dodoma
The most important use of lithium is in rechargeable batteries for mobile phones, laptops, digital cameras and electric vehicles. Lithium is also used in some non-rechargeable batteries for things like heart pacemakers, toys and clocks.
Lithium metal is made into alloys with aluminium and magnesium, improving their strength and making them lighter. A magnesium-lithium alloy is used for armour plating. Aluminium-lithium alloys are used in aircraft, bicycle frames and high-speed trains.
Lithium oxide is used in special glasses and glass ceramics. Lithium chloride is one of the most hygroscopic materials known, and is used in air conditioning and industrial drying systems (as is lithium bromide). Lithium stearate is used as an all-purpose and high-temperature lubricant. Lithium carbonate is used in drugs to treat manic depression, although its action on the brain is still not fully understood. Lithium hydride is used as a means of storing hydrogen for use as a fuel
