Commissioning and Operation of the 800 TPH Heavy Medium Cyclone Plant at Mount Isa Mines Limited

The heavy medium cyclone plant for the preconcentration of silver-lead-zinc ore prior to grinding and flotation was commissioned in August 1982. This paper details the measures taken to get the plant up to design performance which involved modifications to the medium densifying and slimes clarifying sections. Operating experiences to date are described with emphasis on the low medium consumption recorded and severe wear on process equipment.
