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.

What is cleavage of Galena?
Cleavage of galena is the tendency of the mineral to break along planes of weakness, resulting in smooth, flat surfaces. Galena exhibits perfect cleavage in three directions at right angles to each other, producing cubic or octahedral shapes. This property is a result of the crystal structure of galena.
