Project Details

The North Star Process Plant SMP installation package consisted of the supply, manufacture, installation, construction testing and pre-commissioning of a magnetite processing plant. This was inclusive of crushing, grinding and classification separation, right through to the production of concentrate and tailings.

Structural Steel

Centrals fabricated, transported and delivered approximately 3,000 T of structural steel and heavy plate work. This included steel utilised for the construction of both wet and dry processing plant, together with the material handling plant including conveyors. All of the conveyors trusses were predressed with idler frames, handrail, grating and mesh in Perth, and transported in modularised form.

Centrals pre-fabricated and modularised process tanks, to allow for efficient installation. This consisted of three tanks, the largest two tanks measured 10 m diameter x 10 m high.

Mechanical Installation

Centrals were contracted to install all mechanical equipment for the entire plant, from crushing through to concentrate production. The processing plant included High Pressure Grinding Roller (HPGR), air classification equipment, dry and wet magnetic separation units, concentrate and tailings thickeners, process and raw tanks, material handling equipment, conveyors, derrick screens, high pressure positive placement pump and miscellaneous motors, pumps and various mechanical items.

The work included the construction and installation of a separate Concentrate Handling Facility.

Piping Installation

Centrals procured, fabricated and installed all piping for the plant, inclusive of raw water, fire water, slurry, hydraulic, tailings, air and instrument piping. Pipe work covered a range of sizes and materials; specialised hydraulic lines, hydraulic gates, grease lines, high-pressure carbon steel piping, rubber-lined carbon steel piping, galvanised steel and HDPE pipework.

Line sizes included 400 NB high pressure piping, 450 NB HDPE down, 25 NB and smaller, for air and instrument piping.
