Abstract: Hydro-cycloning of plant tailings is an often used tool to produce relatively coarse free draining sand (cyclone underflow) for Tailing Storage Facility (TSF) embankment construction. This paper outlines the available choices and design considerations involved for the minimization of sand production costs by cyclone, looking among others at parameters such as sand yield, water recovery, and consistency of sand quality. A number of changes in drivers to the disposal of tailings make this a relevant subject. Previously not as specifically managed and regulated, the sand quality specification has become considerably more stringent. This and the generally finer grind required for more difficult and lower grade ores often requires double stage cycloning to produce the necessary sand quality. At the same time there have been new advances in cyclone technology. In many parts of the world a shortage of water impacts mining projects. As water is an inherent part of the hydro-cyclone operation, the sand production by cyclone is an integral part of the water management of a tailing management facility.[All papers were considered for technical and language appropriateness by the organizing committee.]
