Terra Nova Technologies Australia (TNT Australia) says it has been awarded the replacement tailings stacker contract by Karara Mining Ltd at its magnetite mine, 200 km southeast of Geraldton in Western Australia.

Karara Mining is the largest mining operation and the first major magnetite mine in the Mid-West of the state. It produces a premium, high-grade concentrate product for export to steelmakers with an expected mine life in excess of 30 years.

The scope of supply will be to replace an existing stacker, TNT Australia said.

In partnership with TNT’s sister company, e2o, a subsidiary of Clough, the contract will include the supply of a new “fit for purpose” heavy-duty stacker able to withstand the rigours of a high-capacity mining environment along with the associated civil works, installation, commissioning and removal of the existing stacker.

This contract will be completed by TNT Australia and e2o, working in partnership as part of the Murray & Roberts ownership group.

The replacement stacker project, which commenced last month, is required to be concluded within 2022 in order to meet Karara’s schedule requirements.

TNG Ltd says an integrated design layout for its flagship Mount Peake vanadium-titanium-iron project in the Northern Territory of Australia has been developed and delivered by Australian engineering and construction company, Clough Projects Australia Pty Ltd.

As announced in October, TNG appointed Clough to work with its project team and SMS group for Mount Peake following a strategic decision to progress a fully-integrated operation at the Mount Peake mine site and given the severe restrictions on travel between Europe and Australia due to the COVID-19 pandemic that have impacted SMS’ ability to deliver a team in Australia.

Clough, together with TNG’s project team, has developed the integrated layout on the basis of the deliverables prepared under the front-end engineering and design study completed by SMS. The layout comprises the beneficiation plant, TIVAN® processing facility and plant utilities located within the mining lease footprint of Mount Peake site.

The integrated plants will be positioned adjacent to the western boundary of the designated mining areas within the company’s existing Mining Lease 29855, which covers an area of 1,460 ha. This area is capable of hosting a fully-integrated operation encompassing mining activities and waste storage, the beneficiation plant, the TIVAN processing facility and non-process infrastructure.

The integrated layout will be “unconstrained” compared with the size and shape requirements at the former Darwin site, TNG said. This offers the potential to capitalise on improving constructability, operability and maintenance for the project, as well as further cost optimisations from integrated infrastructure.

TNG has now commissioned Clough to progress value engineering to optimise outcomes in cost/schedule; and design aspects incorporating, civil, structural and architectural, mechanical, piping, electrical and instrumentation engineering disciplines, logistics and non-process infrastructure.

Clough will work with TNG’s project team and have support from SMS to undertake this next engineering and design stage and deliver an updated capital cost estimate for the development of Mount Peake, with this stage expected to be completed by May 2022.

TNG’s Managing Director and CEO, Paul Burton, said: “The completion of this design paves the way for value engineering and final design work to commence, which in turn will underpin an updated capital cost estimate and pave the way for project finance completion.”

Clough’s CEO and Managing Director, Peter Bennett, added: “We are excited with our ongoing collaboration with TNG on their Mount Peake project as we develop sustainable solutions for the resources sector in Australia. We are proud of our role and long history of delivering world-class engineering and construction projects and critical infrastructure both in Australia and overseas.”

Located 235 km north of Alice Springs, Mount Peake is expected to be a long-life project producing a suite of high-quality, high-purity strategic products for global markets including vanadium pentoxide, titanium dioxide pigment and iron ore fines. The project, which is expected to be a top-10 global producer, has received Major Project Status from the Northern Territory and Federal Governments.

TNG Ltd has appointed a subsidiary of engineering and construction company, Clough, to work with TNG’s project development team and the SMS Group on its flagship Mount Peake vanadium-titanium-iron project in the Northern Territory of Australia.

TNG announced in September that it had decided to progress development of the project with a fully-integrated mining and processing operation within its existing mining leases. As part of this strategy, it was considered by the TNG team important to have a suitable Australian-based engineering group on board.

Following a tender process, Clough Projects Australia Pty Ltd was selected to work with TNG’s team to initially develop an optimised plant layout for the integration of the TIVAN® processing facility (TPF) and beneficiation plant at the mine site, on the basis of the deliverables prepared under the front-end engineering and design (FEED) study completed by SMS group.

Clough, TNG says, will work with SMS and TNG’s team given the severe restrictions on travel between Europe and Australia due to the COVID-19 pandemic that have impacted SMS’ ability to deliver a team in Australia.

TNG previously engaged Clough to assess the definitive feasibility study for the project and this new contract expands on this early work to progress the overall mine development, it says.

The optimised layout will be unconstrained compared with the size and shape requirements at the former Darwin site. This offers the potential to capitalise on improving constructability, operability and maintenance for the project, as well as further cost optimisations from integrated infrastructure, the company says.

The integrated plants will be positioned within the company’s existing Mining Lease 29855, which has a size of 1,460 ha. This area is capable of hosting a fully-integrated operation encompassing mining activities and waste storage, the beneficiation plant, the TPF and non-process infrastructure, according to TNG.

TNG’s Managing Director & CEO, Paul Burton, said: “From a strategic and logistical perspective given the continued global COVID-19-related travel restrictions, it is an advantage to have a locally-based engineering group working on this phase of the Mount Peake project with TNG and SMS.

“We expect the integrated plant layout will pave the way for further optimisation work that will tie back into the recently completed FEED study. These work programs are already underway. We look forward to working closely with Clough and our other engineering partners to rapidly advance the Mount Peake project.”

Located 235 km north of Alice Springs, Mount Peake is expected to be a long-life project producing a suite of high-quality, high-purity strategic products for global markets including vanadium pentoxide, titanium dioxide pigment and iron ore fines. The project, which is expected to be a top-10 global producer, has received Major Project Status from the Northern Territory and Federal Governments.

Alcore’s CORE plans move forward with Clough engineering appointment

Alcore Ltd has executed a contract with major Australia engineering firm, Clough, to help with the design and construction of the first Alcore production plant.

Clough, which will be represented by Clough Projects Australia Pty on the project, has been investigating the CORE technology that will be used by Alcore for several years and is ready for a smooth entry into the Alcore project, the company said.

Alcore says the engineering firm’s in-house skills and expertise provides the full spectrum of capabilities needed, including: concept evaluation & regulatory approvals; project feasibility studies; design, specialised process engineering, electrical controls & instrumentation; and construction, process optimisation and debottlenecking.

Alcore is a 90%-owned subsidiary of Australian Bauxite, which has the global exclusive rights to the aluminium-related portion of CORE Technology (patent application). After six months of test work, Alcore has committed to the best strategy for the first commercial plant called “Refine & Recycle”, whereby by-products from aluminium smelters will be converted into aluminium fluoride to be sold back to the smelters as an essential electrolyte for smelting, it said.

“This strategy has highest profit and fastest growth potential worldwide.”

Plants can be replicated adjacent to aluminium smelters throughout the western world that seek higher environmental credits for recycling by-products, reducing emissions, lowering costs and reducing their dependence on imported aluminium fluoride, according to Alcore.

Alcore can refine two smelter by-products, one with high aluminium (~85% Al) and the second with high fluorine (~55% F), so that all aluminium fluoride components are freely available, it says.

Phillip Hall, Alcore’s Chief Operating Officer, said: “Clough is an ideal engineer for Alcore’s transition from the lab research stage to its first commercial plant. Clough’s long-term association with this technology augers well for good teamwork.

“Alcore is now fully-resourced on technology, having also appointed Dr Mark Cooksey, a senior CSIRO chemical engineer with over 22 years’ experience in the aluminium smelting industry.”

Alcore plans to build its first plant at Bell Bay, in Tasmania, Australia.

Clough, as part of Acciona Clough Joint Venture (ACJV), says it has been awarded by Main Roads WA the construction of Great Northern highway road over rail bridge and access road intersection for the Rio Tinto-owned Koodaideri iron ore mine in the Pilbara of Western Australia.

The scope of works includes the construction of 3.6 km of road for the approaches to the bridge over rail, the construction of the bridge over rail, and construction of side road upgrades of the Great Northern Highway and Koodaideri Mine Access Road intersection, Clough said. This is the second transportation infrastructure project awarded to ACJV this year – the first being a civil works contract for the construction of the northern rail formation for Koodaideri.

Clough CEO and Managing Director, Peter Bennett, said: “Our history with Main Roads started in 1957 and we are proud to continue being part of the ongoing development of WA’s transport infrastructure.”

Koodaideri will deliver a new production hub for Rio Tinto’s iron ore business in the Pilbara, incorporating a processing plant and infrastructure including a 166 km rail line connecting the mine to the existing network.

Construction on Koodaideri Phase 1 started this year with first production expected in late 2021. Once complete, the mine will have an annual capacity of 43 Mt, underpinning production of the company’s flagship iron ore product, Pilbara Blend. The project will help sustain Rio Tinto’s existing production capacity by replacing depletion elsewhere in the system, the miner says.

Clough, as part as the Acciona Clough joint venture, has been awarded a civil works contract for the construction of the northern rail formation for the Rio Tinto Koodaideri iron ore project, in Western Australia.

Clough CEO and Managing Director, Peter Bennett, said: “We are excited with the opportunity to work with Rio Tinto Iron Ore to deliver its vision for the Koodaideri project as we continue to grow our presence in Western Australia’s iron ore developments.”

Bennett said the execution of the contract would create more than 200 new jobs, with the scope including 100 km of rail formation earthworks, culverts, bridge construction, access roads and level crossings.

“Clough is a proudly Western Australian engineering and construction company with a proven history of delivering world-class projects with outstanding safety and quality results in Australia and overseas,” he added.

The engineering and construction company is celebrating its 100th year of operation.

The Koodaideri project is a greenfield mine development for Rio Tinto Iron Ore, in the East Pilbara mining region. The mine will initially be developed with an annual capacity of 43 Mt. To allow the transportation of iron ore product to either Dampier or Cape Lambert, the project requires a 170 km rail spur to connect the Koodaideri mine to the existing Rio Tinto Iron Ore rail network, just south of Lyre Siding at Numbat.

WorleyParsons is carrying out the EPCM contract for the project, while FLSmidth said this week that it will bring the latest 3D smart design to the development.

The project has been designed to use an increased level of automation and digitisation, helping to deliver a safer and more productive mine, which is expected to be Rio Tinto’s lowest cost contributor to its industry benchmark Pilbara Blend product.
