Abstract:
Ciba® RheomaxTM ETD products are specialty chemicals which provide a unique chemical approach to
tailings treatment. They are applied in arid areas where water is scarce and also at mining operations where
improved footprint is required for either land rehabilitation purposes or to simply achieve faster trafficable
surfaces.
This alternative technology was investigated on ferrochrome slime that was deposited onto concrete slab-
lined tailings dam at ASA metals in South Africa. The physical characteristics of the chemically treated
deposit were compared with that of the untreated material during the trial period. The RheomaxTM ETD
thickened slime provided an excellent footprint and therefore successfully reduced the turnover cycle of the
tailings dam. This paper discusses the challenges encountered in this case study during the implementation
and optimisation of RheomaxTM products.
