From our Ore to Your Door - Episode 12: Magnesite Stockpiling, Reclaiming and Blending - Parkhurst
Stockpiling:
Magnesite ore is delivered 70kms by truck to Parkhurst from QMAG’s Kunwarara mine site. To maintain production demand, typically 30 truckloads of magnesite deliveries are required each day. When the ore reaches Parkhurst, it is stored in stockpiles of several thousand tonnes, with each stockpile graded by its chemical purity.
Various stockpiles are generally constructed based on differing previously analysed grades of ore so that they can be used for blending to the required chemical requirements.
Incoming loads of magnesite are emptied into the dump hopper at the southern end of the stockpile area and stacked onto the designated stockpile zone. There are eight zones having the capacity to store 30Kmt of magnesite serviceable by the stacker. There are three additional zones not serviced by the stacker where trucks can dump directly onto the stockpile storage area.
A travelling, luffing stacker moves along railway lines and is used in conjunction with a conveyor running through the centre of the stockpile area to deliver product from the receival hopper to the specified zone.
Reclaiming:
Magnesite is reclaimed from the stockpiles by frontend loader and delivered to any one of three reclaim hoppers based on the stockpile location. Conveyor transfer systems deliver the material from the reclaim hoppers to each Multi-Hearth Furnace feed bin ready for processing.
To meet the specific magnesite chemical composition for each MHF, a ratio of bucket loads from various stockpiles is calculated. These loading instructions are issued to the frontend loader driver to ensure the correct blend is being used for each MHF.

From our Ore to Your Door - Episode 7 - Mining Operations
QMAG currently mines 4 million tonnes of ore per year, from six to eight different pits.
We choose pits based on their magnesite content and contaminant concentrations. There are always at least two pits mined simultaneously to provide the Parkhurst plant with enough material at suitable quality to support our full suite of products.
From our Ore to Your Door - Episode 6 - Mining Pit Development
With exploration, drilling and planning complete, it’s time to start mining. First, surveyors stake out the boundary of the area to be mined. A clearing permit verifies that the area to be mined is within the active lease, has
been cleared by the local Land Council, and has the correct government permit to be mined. Now the pit development can begin.
Visitors to Kunwarara
We were thrilled to welcome Matthew Canavan and Michelle Landry to our mine last week! It was an exciting opportunity to give them an in-depth look at our "Ore to Your Door" process and share the remarkable stories of the local businesses that enrich our community.
The falcons are back!
The final days of winter saw some wonderful news at QMAG’s Parkhurst facility in Rockhampton, Australia – the much loved (and respected) resident peregrine falcons are nesting!
