Abstract
A method and installation for forming and maintaining a slurry are disclosed. The method withdraws a slurry from a reservoir and directs it at a heap of solid material from which the slurry is drained into the reservoir, the slurry containing additional solid material from the heap to increase its specific gravity. The volume of slurry in the reservoir and its specific gravity are controlled. The installation comprises a support having a support surface which slopes to permit slurry to drain therefrom A reservoir receives slurry draining from the support and has a liquid feed. A pump withdraws the slurry from the reservoir and pumps it to a spray nozzle for spraying slurry at a heap of material on the support.
