Aug 19, 2011· Bismuth is the 83rd chemical element on the periodic table with the symbol of Bi. It has a silvery white color and was often mistaken for lead or tin before its discovery. The first person to show that it was different from these two elements was Claude François Geoffroy in 1753 and he is credited with its discovery.
Reynolds began exporting bauxite from Ocho Rios in June 1952, and Kaiser followed a year later from Port Kaiser on the south coast. Alcan built the first alumina processing plant near its mines at Kirkvine, Manchester, and in early 1952 began shipping alumina from Port Esquivel. This was the beginning of the industry in Jamaica.
