Bayer process. The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer. Bauxite, the most important ore of aluminium, contains only 3060% aluminium oxide (Al 2 O 3 ), the rest being a mixture of silica, various iron oxides, and titanium dioxide. [1]

Uses. Bauxite is a resource in Workers Resources. Bauxite is produced in a bauxite processing plant. The plant processes raw bauxite into bauxite. At maximum efficiency and with 25 workers, a bauxite processing plant can process maximum of 125t of raw bauxite to produce 75t of Bauxite per workday. This means the conversion ratio raw bauxite ...

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.
