Processing of bauxite for smelter grade alumina is quite sensitive to bauxite recovery and total cost for processing of ore, particularly in wet beneficiation. On the other hand, owing to homogeneous nature and consistent quality, some alumina refineries prefer washed ore compared to simple crushed run-of-mine (ROM) bauxite.

Bauxite is an aluminium ore found in deposits around the world. Once the ore is mined out of the ground, the red bauxite rock is crushed and dissolved into a white alumina powder, using what is known as the Bayer process. This alumina powder is then smelted into aluminium metal. Australia is the world’s largest producers of bauxite.get price

In October aluminium prices spiked 62% to $2934 per tonne, up from $2004 per tonne in January and $1806 per tonne in October 2020. This came as China began to decrease due to restrictions on energy usage – because the process of aluminium smelting is super energy intensive so not great for CO2 emissions targets.
