The abundance of U-235 in most uranium ore is about 0.7.
Yes, uranium ore is radioactive. The potential risks associated with its radioactivity include exposure to harmful radiation, which can lead to increased risk of cancer, genetic mutations, and other health issues. Proper handling and disposal of uranium ore is important to minimize these risks.
Uranium ore contains only a small percentage of uranium for one thing, but also natural uranium contains only 0.7 percent U235. Even pure natural uranium will not cause a chain reaction unless it is surrounded by a moderator such as pure graphite or heavy water. Ordinary water will not allow this to happen.
The uranium used in a CANDU reactor primarily exists as uranium-238, a naturally occurring isotope found in various minerals, with a small percentage of uranium-235. It is extracted from uranium ore through milling and chemical processes to increase the concentration of uranium-235 for use as nuclear fuel in reactors.
Uranium is extracted from the earth by mining; after this it is processed by chemical/metallurgical procedures in useful materials as nuclear fuels, nuclear weapons, chemicals for the industry and laboratory etc.
Mainly because only about 0.7% of uranium is the isotope uranium-235, which is easily fissionable. It is believed that in Earth's remote past, there were such chain reactions - natural reactors - at a time when the percentage of U-235 was higher.
An important ore of uranium is called Pitchblende.
No, iron ore and uranium ore are two different types of ores. Iron ore is a mineral that is a source of iron while uranium ore is a mineral that contains uranium, a radioactive element used for nuclear energy production.
Pitchblende is a name for uraninite, a radioactive mineral from which uranium ore is extracted. The composition of pitchblende can include uranium oxide (UO2) and triuranium octoxide (U3O8), along with lead oxide and pockets of helium.Pitchblende is a radioactive, uranium-rich mineral and ore. It has a chemical composition that is largely UO2, but also contains UO3 and oxides of lead, thorium, and rare earth elements. It is known as pitchblende due to its black color and high density. It is also commonly referred to as Uraninite.
The process of isolating polonium and radium from uranium ore is called "uranium ore processing" or "uranium enrichment." This involves a series of chemical and physical separation techniques to extract the desired elements from the ore.
Silver is not extracted from uranium ores.

Uraninite, AKA pitchblende, is an ore of uranium.
copper
Polonium is a rare radioactive element on Earth. It is not found in nature in large quantities and is mostly produced as a byproduct of uranium and thorium decay. The abundance of polonium in the Earth's crust is estimated to be about 0.1 parts per trillion.
coal, platinum, copper, uranium nd iron ore
Uraninite, also known as pitchblende, is one of the most radioactive rocks in the world. It is a uranium ore that can contain high concentrations of radioactive elements such as uranium and radium.
In the western states from Texas to Arizona and as far north as Colorado and Wyoming. Most good quality uranium ore in these locations is mixed with vanadium ore, and in the early days reworking vanadium mine tailings was an effective way to obtain uranium.
