Uranium is the element being referred to here. It is named after the planet Uranus, the 7th planet from the sun. Uranium is a nuclear fuel source that is highly efficient; just one pound of uranium can produce as much energy as 1500 tons of coal.
A Wikipedia article (see link below) gives the concentration of uranium in ore as 0.01 to 0.25 percent, which is a wide range. If we take 0.1 percent as typical, then 1 tonne (1000Kg) of ore would produce 1 Kg of uranium. This is natural uranium, which is normally enriched by about six times to produce suitable enriched uranium for fuel, so you can say that about 6 tonnes of ore would be needed to give 1 Kg of enriched uranium, but there is considerable variation of this from one source of ore to another
Approx. 70 000 kg day.
To determine the amount of oxygen combined in the sample of pitchblende, we use the chemical formula of pitchblende, which is U3O8. The molar ratio of uranium to oxygen in U3O8 is 3:8. Given that there are 1.8 tons of uranium in the sample, we calculate the amount of oxygen by multiplying 1.8 tons of uranium by the ratio of oxygen to uranium (8/3). This yields approximately 4.8 tons of oxygen combined in the sample of pitchblende.
Uranium is used as a fuel because it produces massive amounts of heat, Around 700 Degrees if controlled, And aver 3000 Degrees if not controlled. This heat is then pumped by tons of water which the Uranium turns into steam which turns the turbines that produce electricity.
That depends on what substance the question refers to. For example . . . Gold: very few tons Diamonds: even fewer tons Enriched uranium: several tons CO2: copious tons Trash: megatons
India produces 285,029,000 tons a year!
It is estimated that Earth possesses about 40 million metric tons of uranium reserves. The metal is primarily found in rocks, seawater, and soil, with the largest deposits located in Australia, Kazakhstan, and Canada. While uranium is a finite resource, current levels of production and consumption are sustainable for the foreseeable future.
At the end of 2008, Australia had 69,310 million metric tons of recoverable coal reserves, 8.9% of the world's total.
Approximately 30,000 kilograms of coal would need to be burned to produce the same amount of energy as is generated by a kilogram of uranium fuel pellet. Uranium fuel has a much higher energy density than coal, making it a more efficient and cleaner source of energy.
The amount of uranium in a nuclear reactor depends on its size and design. On average, a typical reactor may contain several tons of uranium fuel in the form of uranium dioxide pellets that are stacked in fuel rods. For example, a 1000-megawatt nuclear reactor may have around 100-150 tons of uranium fuel.
