Detailed explanation-1: -The primary uranium ore mineral is uraninite (UO2) (previously known as pitchblende). A range of other uranium minerals can be found in various deposits. These include carnotite, tyuyamunite, torbernite and autunite.
Detailed explanation-2: -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.
Detailed explanation-3: -Pitch blende is also called uraninite. It is a mineral of uranium-containing and . It is our primary source of uranium and the mineral is black in colour, like ‘pitch’. The term ‘blende’ came from the German miners who believed it contained many different metals all blended together.
