Electrofused magnesia (EFM)

QMAG’s EFM is used as a raw material for refractory bricks used in iron and steel making furnaces and associated equipment where high wear resistance is required. With high melting point secondary phases, these chemical properties combined with the high density and very large periclase crystal size, ensures that QMAG’s EFM products are considered amongst the best available in the world.

Industries

The high temperatures of steel, iron, cement, glass and ceramics production require thermal insulation in the form of refractory bricks using our DBM and EFM magnesia products. The agricultural sector uses our magnesia as a vital animal feed supplement and fertilizer to maintain plant and animal health. We support the path to net zero carbon emissions by supplying our magnesia to precipitate nickel and cobalt used in EV batteries. Our magnesia is also used in numerous industrial applications such as waste water treatment and the pulp and paper industry.

Falcon Update

The peregrine falcons at QMAG’s Parkhurst processing facility are breeding again after an unfortunate setback in September.

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
