Most backfill used in South African gold mines is prepared by desliming metallurgical plant tailings with hydrocyclones. The behaviour and quality of the backfill produced is a sensitive function of its moisture content and particle size distribution. In order to prepare backfill of adequate quality it is necessary to predict the performance of hydrocyclones …
