Bismuth extraction
WebBismuth, which has been known since ancient times, was often confused with leadand tin. By the 1400s, people had begun to suspect that bismuth was a distinct chemical element, but it was not isolated until 1753. In 1595 Andreas Libavius confused it with antimony, and in 1675 Nicolas Lemery with zinc. WebBismuth can also be extracted from Pepto-Bismol tablets. Bismuth’s name comes from the German word “wissmuth” and the Latin word “bisemutum”, which means white mass. The Incas utilized bismuth by combining it with copper and tin to produce knives. Ancient Egypt used bismoclite for cosmetic purposes. Bismuth-209 is an isotope.
