Aberfoyle's Hellyer Division has filtered very fine flotation concentrates using two different makes of pressure filter. At the Luina concentrator a Larox pressure filter was used to treat a combined Pb + Zn or bulk concentrate. At the Hellyer concentrator two Lasta pressure filters are being used to filter copper/silver, lead, zinc and bulk concentrates. Operating parameters and performance at both operations are described. In both concentrators it was found that correct cloth selection was critical and that cloth failures contributed significantly to downtime. Thorough preventative maintenance progammes were required to ensure adequate availability of both makes of filter.
