Vacuum Filtration

Three horizontal vacuum belt filters each 85 m2 were supplied for this expansion project. Extreme care was taken to ensure the design adequately catered to the requirements of this “sticky” ore. The units were delivered in modular form, with integrated walkways and pre-wired, high spec instrumentation including in-line moisture analysis.

Three 122m2 horizontal vacuum belt filters to dewater coal concentrates were delivered to site in what was at the time an industry first; two module halves that significantly reduced site erection time. The overall project timeframe was demanding and this novel delivery method gave our customer a six week benefit to the overall project schedule.

Jord investigated a range of filtration technologies for a low cost solution to dewater magnetite concentrate recovered from a previous waste tailings stream. A ceramic disc filter was ultimately selected to meet the low moisture and low energy cost brief.

Jord undertook a turnkey brownfield upgrade of the Mt Isa lead filtration plant. This brownfields project involved significant complexity in order meet demanding environmental and safety requirements of working within an operating plant contaminated lead environment. Jord delivered on time the turnkey removal and replacement of the existing filter and install its replacement with zero environmental or safety incidents.

On the back of extensive laboratory test work, Jord effectively sized and supplied a modular horizontal vacuum belt filter for this service. Further complicated by the need to span an existing road way, Jord worked hand in hand with the client to propose a self-supporting filter of extended length, complete with integral walkways. The unit was trucked some 4,000 km by road, before being barged the rest of the way to the plant, located on Groote Island.

Significant caustic losses in an alumina refinery process was the commercial imperative that drove the installation of a horizontal vacuum belt for a sand washing project. In addition to removing caustic chemical residue from this tailings waste stream, a saleable sand product was recovered and valuable caustic solution was returned to the alumina process.
