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.
