(> -1 mm). Currently the slimes and tailings are disposed of to a slimes dam comprising an approximately 80 m high embank-ment with a length of about 1 100 m and a capacity of approxi-mately 58 x 106 m3, (Cutting et al., 1996). Pipes with a diameter of 30 to 40 mm are used to pump slimes to the dam.
of slime is likely to slide and cause the dam to break away. The procedure usually adopted in such cases is to separate the tailing into coarse sand and fines in a classifier, and to use the coarse product to build up the wall ; the remainder of the pulp is discharged into the interior of the dam.
During the March quarter, 36 boreholes were drilled in Blyvoor's seven slimes dams, showing U3O8 concentrations in the range of 39 to 93 ppm [0.0033 - 0.0079% U]. Volumes of the slimes dams were surveyed and their total tonnage calculated at 107.7 million tonnes.
