When did the Australian rail freight operator, whose main commodities included Aluminium oxide, become part of QR National?
Aluminium oxide Aluminium oxide (British English) or aluminum oxide (American English) is a chemical compound of aluminium and oxygen with the chemical formula Al O . It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium(III) oxide. It is commonly called alumina, and may also be called aloxide, aloxite, or alundum depending on particular forms or applications. It occurs naturally in its crystalline polymorphic phase α-AlO as the mineral corundum, varieties of which form the precious gemstones ruby and sapphire. AlO is significant in its use to produce aluminium metal, as an abrasive owing to its hardness, and as a refractory material owing to its high melting point.
Mount Perry railway line The Mount Perry Branch Railway is a closed railway line in Central Queensland, Australia. In 1869 copper was discovered at Mount Perry in the Bundaberg region of Queensland, Australia and the township grew rapidly. A railway to the coast was essential to provide cheap transport and make the mining of low percentage ore viable. Maryborough and Bundaberg vied for the opportunity to be the terminus and the latter city was successful.
