Catalog Page for PIA18686

The world's largest bauxite mine is found near Weipa, Queensland, Australia. The rich aluminum deposits were first recognized on the end of the Cape York Peninsula in 1955, and mining began in 1960. Weipa is just south of Duyfken Point, a location thought to be the first recorded point of European contact with the Australia continent by Dutch explorer Willem Janszoon in 1606. Get price
