Alcoa has continued the trend for vertically integrated aluminium producers to sell their bauxite to third parties, with a new sale agreement for its Australian bauxite announced on Tuesday.

In their first contract to sell bauxite from Western Australia to a third party, Alcoa and its Australian joint-venture partner Alumina Limited have agreed to sell 400,000 tonnes of bauxite from the Huntly mine near the town of Dwellingup.
