WebCurie needed to refine several tons of pitchblende in order to obtain tiny amounts of polonium and radium, another radioactive element discovered by Curie. One ton of uranium ore contains only about 100 micrograms (0.0001 grams) of polonium. Due to its scarcity, polonium is usually produced by bombarding bismuth-209 with neutrons in a … WebAntimony is not an abundant element but is found in small quantities in over 100 mineral species. It is most often found as antimony(III) sulfide. It is extracted by roasting the antimony(III) sulfide to the oxide, and then reducing with carbon. Antimony can also be found as the native metal. China produces 88% of the world’s antimony.
