Uraninite - Wikipedia Uraninite, also known as pitchblende, is a radioactive, uranium -rich mineral and ore with a chemical composition that is largely UO 2 but because of oxidation typically contains variable proportions of U 3 O 8
Pitchblende | Radioactive, Uranium, Thorium | Britannica Pitchblende, amorphous, black, pitchy form of the crystalline uranium oxide mineral uraninite (q v ); it is one of the primary mineral ores of uranium, containing 50–80 percent of that element Three chemical elements were first discovered in pitchblende: uranium by the German chemist Martin
Uraninite: A radioactive mineral and ore of uranium Uraninite, also known as pitchblende, is a radioactive mineral and the most important ore of uranium We have uraninite photos, physical properties, and information about geologic occurrence, alteration products, and the role of uraninite in the discovery of radioactivity
What Is Pitchblende? (Uraninite) - ThoughtCo When learning about the element uranium, the term pitchblende commonly pops up What is pitchblende and what does it have to do with uranium? Pitchblende, also known by the name uraninite, is a mineral comprised mainly of oxides of the element uranium, UO 2, and UO 3 It is the primary ore of uranium The mineral is black in color, like 'pitch'
Uraninite Mineral Information and Facts Scientific facts about the mineral Uraninite, including characteristics and industrial uses of pitchblende and uranium ore
Pitchblende: Definition, Examples Quiz - ultimatelexicon. com Pitchblende, also known as uraninite, is a radioactive mineral comprised mainly of uranium oxide (UO2) and is the primary ore of uranium It appears as a black, pitch-like substance with a greasy or resinous luster and has been historically prominent due to its radioactive properties and significant in the fields of nuclear science and geology
PITCHBLENDE Definition Meaning - Merriam-Webster The meaning of PITCHBLENDE is a brown to black mineral that consists of massive uraninite, has a distinctive luster, contains radium, and is the chief ore-mineral source of uranium
pitchblende - Infoplease Pitchblende is greenish, brownish, or black in color, with a pitchy to submetallic luster The uranium yield is from 50% to 80% Uraninite, a closely related ore richer in uranium (uranium dioxide), commonly crystallizes in the cubic system It yields 65% to 80% uranium and has a specific gravity somewhat higher than that of pitchblende
Pitchblende Uranium Ore - 911Metallurgist Pitchblende Uranium Ore Pitchblende or uraninite, consists mostly of uranium oxides It is a pitch-black, greenish or brownish black mineral, green or brown when finely powdered; it has a smooth or conchoidal break, and is very heavy Pitchblende is found in pegmatite dikes, sometimes, as in Cornwall, England, associated with tinstone
