Potential radiological impacts from mining and processing are mainly due to the radiation associated with radionuclides 232 Th and 238 U and their decay products, and there is a relatively small, essentially negligible, contribution to radiation dose estimates from 40 K in the bauxite. The approximate K chemical concentration of wt % in bauxite ore corresponds to a K40 activity of ...
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.

As well as reducing bauxite processing costs, this process makes the remaining red mud less polluting and easier to handle a significant benefit. The process has been proven technically and economically at labscale. Now, we're planning to further test the process at a bauxite refining plant in the next step toward commercialisation.
Bauxite is the main source of the rare metal gallium. During the processing of bauxite to alumina in the Bayer process, gallium accumulates in the sodium hydroxide liquor. From this it can be extracted by a variety of methods. The most recent is the use of ionexchange resin.
