Most bauxite mines produce Direct Shipping Ore (DSO) bauxite as they require no processing before being sent to a refinery. However, some bauxites require some form of screening (either wet or dry) to remove the fine grained material to improve the grade and/or handleability.
Most bauxite ores are not processed before refining, ... By the 1960s, world bauxite production had reached 40 million tonnes. It is now around 260 million tonnes. In 2016, Australia is the world's largest bauxite producer, producing 80 million tonnes.
Global bauxite production was estimated at 279.7 million tonnes (Mt) in 2015, down 0.3% YoY, attributed to production declines in Brazil and China. Indonesia's bauxite production too dropped significantly from 55.7Mt in 2013 to only 500kt in 2014, owing to the ban on exports of raw ores imposed at the beginning of 2014.
