Abstract: The rate of evaporation from thickened tailings is an important parameter for the management of surface 
deposition.  Promoting evaporation in a freshly-deposited layer is desirable up to a point, since evaporation 
causes densification and strength gain, but excess evaporation will desaturate the tailings and consequently 
increase the risk of acid generation.  Therefore, the ability to predict the rate of evaporation to some degree 
of accuracy would be a substantial advantage in deposition planning.  This study, part of a larger project 
researching the surface deposition of non-plastic, thickened tailings at the Bulyanhulu Gold Mine in 
Tanzania, investigates drying from thickened gold tailings in the laboratory and in the field.  Material 
presented in this paper includes laboratory comparison of evaporation from a small column (0.3 m diameter 
by 0.2 m in height) to evaporation from larger-scale tests (2 m by 1 m in plan and 0.1 m in thickness) 
performed on tailings from Bulyanhulu.  These laboratory results are compared with field measurements.
