Radium is difficult to extract from pitchblende because it occurs in very low concentrations and is chemically similar to other radioactive elements in the ore. Its extraction requires a series of complex chemical and physical processes, such as acid leaching, precipitation, and purification, which are time-consuming and costly. Additionally, the handling of radium is hazardous due to its high radioactivity, requiring specialized equipment and precautions.
pitchblende was the first, but any good uranium ore will do as it is a daughter element of uranium's decay.
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.
the main element extracted was radium
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.
You think probably to radium (Ra) and polonium (Po).
in ore of pitchblende
Radium was first discovered in an ore called pitchblende
Yes. Pitchblende contains one gram of radium per seven tons. It is radioactive.
Radium is an element itself. It was isolated by Marie Curie from Pitchblende, an ore of Uranium.

The Curie couple brought the source (pitchblende) from North Bohemia

Uranium minerals are: pitchblende, carnotite, autunite, coffinite, etc.
Radium was discovered by the Curies in France in 1898, in samples of pitchblende which were found to be radioactive after removal of the uranium.
Yes, pitchblende is an important ore of uranium which also contains traces of other radioactive elements like radium and thorium. Plutonium can be produced artificially from uranium but is not naturally found in pitchblende.
