Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.

Alumina calcination Calcination is the final stage of the Bayer process, in which bauxite is digested with caustic soda to first extract and then precipitate a pure aluminium hydroxide (hydrate). The hydrate from the Bayer process is then calcined to alumina in a CFB. This step was earlier carried out in rotary kilns, but today all new capa-city is

Soft limestone feeds can be used, but they produce a lot of fines during calcination. Lower fuel requirements in PRKs is due to better heat exchange in the preheater (beginning of de-carbonization). The disadvantages include formation of rings (coal ashes, calcium sulphates, clay), and pre-heater is an additional piece of equipment to maintain.

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.
