31-12-2016· In 2017, the Australian industry consisted of: Four long-term bauxite mines at Weipa, Gove, Huntly-Willowdale and Boddington and two new, small mines at Hey Point and Bald Hill (Figure 1). Six alumina refineries at Yarwun and QAL in Queensland, and Kwinana, Pinjarra; Wagerup and Worsley in Western Australia (Figure 1).Bauxite | Geoscience Australia,The principal minerals in bauxite are gibbsite (Al 2 O 3.3H 2 O), boehmite (Al 2 O 3.H 2 O) and diaspore, which has the same composition as boehmite, but is denser and harder. Australia is the world's largest producer of bauxite, representing 28% of global production in 2012.Bauxite mining in Australia - Wikipedia,In Australia, bauxite is mined using an open-cut method. This is possible because most bauxite in Australia can be found at or relatively close to the surface and is easily accessible by this method. Open cut mining involves first removing the area above the bauxite ore called the overburden.
