The principal problem is simply that so much ore is required to provide small amounts of radium. About one ton of pitchblende yields about one seventh of a gram of radium.

Is radium easy to find?
Radium exist in very low concentrations in uranium and thorium ores; it is very difficult and expensive to extract radium from these ores.
Which mineral is radium obtained?
pitchblende was the first, but any good uranium ore will do as it is a daughter element of uranium's decay.
What kind of rock is radium found in?
Radium was discovered by Marie Sklodowska Curie, a Polish chemist, and Pierre Curie, a French chemist, in 1898. Marie Curie obtained radium from pitchblende, a material that contains uranium, after noticing that unrefined pitchblende was more radioactive than the uranium that was separated from it. She reasoned that pitchblende must contain at least one other radioactive element. Curie needed to refine several tons of pitchblende in order to obtain tiny amounts of radium and polonium, another radioactive element discovered by Curie. One ton of uranium ore contains only about 0.14 grams of radium. Today, radium can be obtained as a byproduct of refining uranium and is usually sold as radium chloride (RaCl2) or radium bromide (RaBr2) and not as a pure material.
Which rare element would you associate with Marie and Pierre curie?
Marie and Pierre Curie isolate radium. On April 20, 1902, Marie and Pierre Curie successfully isolate radioactive radium salts from the mineral pitchblende in their laboratory in Paris. In 1898, the Curies discovered the existence of the elements radium and polonium in their research of pitchblende.
What radioactive element was extracted from carnotite and pitchblende?
the main element extracted was radium
How do you find radium?
in ore of pitchblende
What does the element radium occur in?
Radium was first discovered in an ore called pitchblende
Is radium easy to find?
Radium exist in very low concentrations in uranium and thorium ores; it is very difficult and expensive to extract radium from these ores.
Is contact with pitchblende dangerous?
Yes. Pitchblende contains one gram of radium per seven tons. It is radioactive.
What element is radium found in?
Radium is an element itself. It was isolated by Marie Curie from Pitchblende, an ore of Uranium.
Which mineral is radium obtained?
pitchblende was the first, but any good uranium ore will do as it is a daughter element of uranium's decay.
Symbol of the element found in pitchblende after uranium has been extracted?
Radium (Ra)

Which country was radium discovered in?
The Curie couple brought the source (pitchblende) from North Bohemia
What radioactive element was extracted from carnotite and pitchblende?
the main element extracted was radium
What was radium discovered for?
Radium was more or less discovered by accident while the Curies were looking for Uranium in samples of Pitchblende. In 1898, they discovered in tiny amounts, Polonium in July, and Radium in December.
