1. Actinium is separated from uranium ores residues, after the extraction of uranium radium and polonium; are used classical methods in chemistry but the process is long and difficult.
2. Actinium isotopes can be also artificially prepared by the intermediate of nuclear reactions as:
Actinium is a natural chemical element but also can be prepared in laboratory.
Actinium is a natural chemical element but also can be prepared in laboratory.
Any compound of actinium is important; actinium is very rare, difficult to be prepared, expensive.
Actinium is a natural chemical element (the isotope 227Ac) but also can be prepared by the intermediate of nuclear reactions.
From Wikipedia "Actinium is found in trace amounts in uranium ore, but more commonly is made in milligram amounts by the neutron irradiation of 226Ra in a nuclear reactor. Actinium metal has been prepared by the reduction of actinium fluoride with lithium vapor at about 1100 to 1300°C."
The cost of actinium can vary depending on the supplier and market conditions. As of now, the price of actinium is around $1,000-$5,000 per gram. Therefore, 100g of actinium would cost approximately $100,000-$500,000.

Actinium was discovered in residues from the uranium and radium extraction from ores. The concentration of Ac is extremely low. But actinium can be prepared and artificially, as a result of nuclear reactions. Andre Louis Debierne (France) discovered actinium in 1899. Friedrich Oskar Giesel (Germany) independently discovered it in 1902 but Debierne is largely credited with the discovery.
Possible uses: neutron source, alpha rays source for radio-therapy
Actinium is a trivalent metal; only in the actinium hydride is divalent.
Actinium may be used in actinium-beryllium neutron sources or in radiotherapy.
Actinium is rarely used:- as actinium-beryllium neutron source- in radiotherapy
