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.

Actinium is found in extremely low concentrations in residues from uranium ores (uraninite, pitchblende).
Actinium is a radioactive metal; no taste !
no actinium is not a magnet no actinium is not a magnet
Possible uses: neutron source, alpha rays source for radio-therapy
Probable actinium was not tested for flammability.
Batteries doesn't contain actinium.
Actinium is found in uranium and thorium ores.
Actinium is found in extremely low concentrations in residues from uranium ores (uraninite, pitchblende).
Discoverers of actinium: Andre Louis Debierne - 1899 Fritz Giesel - 1902 Actinium is found in uranium minerals.
Actinium exist in minute traces in uranium and thorium ores.
Actinium exist in minute traces associated with uranium or thorium ores.
Actinium exist in all uranium minerals: ex. uraninite (pitchblende).
Actinium is found in very low concentrations in uranium ores, probably as an oxyde.
Actinium is separated from pitchblende. Actinium, AC, is found in uranium ore, a product of radioactive decay of uranium and ?æother unstable elements.
in 1899 in France.
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."
