PERTH (miningweekly.com) – ASX-listed TNG is weighing the use of hydrogen reductant at its Mt Peake operation, in the Northern Territory, to reduce carbon emissions.

The company on Monday announced that it had engaged Metso Outotec to conduct a study of the Mt Peake project to assess the use of hydrogen reduction within the TIVAN process, and the integration of its technology into the TIVAN flowsheet.

The study follows positive testwork undertaken by Metso Outotec that confirmed the suitability of Mt Peake titanomagnetite concentrate to hydrogen reduction.

In parallel, TNG is also undertaking with strategic partner SMS group the development of hydrogen production technology at Mt Peake.

“Building on the positive results from the preliminary testwork program, we’re very encouraged by the opportunity to potentially reduce carbon emissions from the processing operation at Mt Peake by using Metso Outotec’s Circored technology. This study also complements our existing partnership with SMS group to investigate green hydrogen production at Mt Peake,” said TNG MD and CEO Paul Burton.

“TNG aspires to make the Mt Peake project a class leader in terms of carbon emissions and the use of renewable energy, and we’re actively assessing opportunities across the mining and processing operation to help us achieve this objective.”

Mt Peake is expected to require a capital investment of A$824-million, according to a 2019 study, and could produce 23.3-million tonnes of magnetite concentrate, based on a two-million-tonne-a-year operation and over a mine life of 37 years.
