Abstract : Bauxite is an ore that mainly contains minerals aluminium oxide, such as Gibbsite (Al2O3.3H2O) and Boehmite (Al2O3.H2O) with clay and minimum of ferrous oxide (Fe2O3) as gangue minerals. The preparation of Crude Bauxite (CBx) is did by using washing method in washing plant to loose the clay from CBx. PT.XY produced 435,1158 m3 clay (tailing) per day and pumping 3287,7158 m3 of water, with 11 segment of sediment pond with each variation of sedimentation. The results of the research and field observation showed that there are steps to analyse the sediment pond. First, calculate the amount of slurry (tailing and water) from washing plant. Second, sampling (before and after of segment). Third, analyse samples by measuring and calculating the percentage of sediment. Fourth, calculate the amount of totally actual sediment of each sample by comparing the percentage of sediment in sample to totally slurry. Fifth, calculate the actual amount of sedimentation on each segments of sediment pond by comparing actual amount of sediment at before segment and actual amount of sediment at after segment. Sixth, testing the sample from the last segment of sediment pond by TSS, TDS, and turbidity test. The result of that steps will got the amount of sedimentation on each segments of sediment pond and value of TSS, TDS, and turbidity.
