Uranium is extracted from mines: open pit, underground, in situ leaching.
The preparation of pure uranium metal (or other compounds) from ores is a long and expensive work.
Chemical engineering processes and other processes are of course involved: radiometric sorting, grinding, dissolving, filtration, separation with ion exchangers, separation by solvent extraction, precipitation, calcination, etc.
Natural francium exist in uranium and thorium ores.Artificial francium is obtained in particle accelerators.
Uranium was discovered But as mineral) in 1789 by Klaproth.In 1841 Peligot obtained the pure metal.
Protactinium is a natural chemical element, found in uranium ores as pitchblende in extremely low concentrations; but protactinium can be obtained artificially by nuclear reactions from 232Th.

yes, it was formed in supernova explosions that occurred before the formation of the solar system
No, Uranium is naturally occurring. But all elements beyond uranium are man-made.
Actinium is a natural element but because is extremely difficult to be separated from ores it is practically obtained artificially in laboratory.
In the nature uranium is found associated with uranium ores but in extremely ultratraces. Plutonium is obtained in industrial quantities, by nuclear reactions, in nuclear reactors.
Uranium and radium, and a number of others, are natural elements found in the ground, and they are radioactive.
Uranium-235, found in natural Uranium at a level of 0.72%Uranium-233, produced in breeder reactors from Thorium-232
francium is found in thorium and uranium ores in the earth's crust obtained by the decay of actinium
Uranium is most commonly found in its natural state within various types of minerals, such as uraninite and pitchblende. These minerals are typically found in igneous rocks or sandstone deposits. Due to its radioactivity and chemical properties, uranium is rarely found in its pure form in nature.
