Bauxite & Alumina Plants – Jamaica Bauxite Institute (JBI)
The plant’s initial design capacity called for 250,000 tonnes of alumina per year, with provision for further expansion in its design. Alumina was first produced at Ewarton Works in October 1959. Today, Kirkvine Works is in a mothballed state after production ceased during the first half of 2009 when depressed market conditions emanating from the Global Financial Crisis rendered operations unviable.

Alumina Refining | The Aluminum Association
Quick Read. Alumina is the common name given to aluminum oxide (Al 2 O 3 ). Alumina is produced from bauxite, an ore that is mined from topsoil in various tropical and subtropical regions. The Bayer process, discovered in 1887, is the primary process by which alumina is extracted from bauxite. To produce pure aluminum, alumina is smelted using the Hall–Héroult electrolytic process.

Aluminium production process
ALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda.
