McKinsey: firms must invest in Remote Operating Centers

It's been a year for remote working with the COVID-19 pandemic - and the mining industry is not exempt from the changes.

Some firms have started to relocate around 15–20 percent of their on-site workforce by setting up “control towers” to facilitate remote working, according to McKinsey's Remote Operating Centers in mining: Unlocking their full potential report, which is helping the industry develop more resilient, responsive, and flexible operating models suited to an increasingly uncertain environment. 

Yet more needs to be done. McKinsey's research unearthed a common theme underpinning the root causes for failure; insufficient emphasis on and investment in developing a robust change-management strategy and subsequent implementation.

It lays the responsibility for change with leaders, who do not set clear expectations of bottom-line impact from ROCs and/or position the ROC with limited authority within the organization. 

Drilling down into the Remote Operating Center (ROC) landscape, it discovers:

  • Some companies have implemented cloud-based systems that aggregate site data into a single data lake that can be accessed, analyzed, and visualized for decision support, creating a “room of screens”.
  • Other companies manage and actively control plant automation systems, fleet management systems, and remote-controlled machines from the ROC. 
  • The most sophisticated companies manage all these functions on a larger geographic scale, covering the value chain from end to end, optimizing post-processed ore logistics and port facilities used by multiple mine sites within a region, with regional parts and supply warehouses monitored across multiple assets for supply-chain optimization. 
  • The larger span of control of such operations helps to maximize best-practice benefits across site assets to drive operational improvements such as predictive maintenance among similar mine fleets. 

Companies usually focused on a combination of four value levers when implementing ROCs:


It advises companies to embrace five key principles when creating value out of ROCs:

  • Define a clear and compelling business case around the value creation for the organization
  • Take a robust approach to organizational integration and change management
  • Ensure the organization is set up to attract and nurture the best industry talent to drive long-term performance and growth 
  • Create the technology backbone of the ROC through technology stack and facilities integration
  • Understand social, environmental, and legal impacts

Rio Tinto partners with ARENA for green hydrogen research

Rio Tinto and the Australian Renewable Energy Agency (ARENA) will study using hydrogen to reduce carbon emissions in alumina refining

Rio Tinto has partnered with the Australian Renewable Energy Agency (ARENA) to study whether hydrogen can replace natural gas in alumina refineries to reduce emissions.

Rio Tinto and ARENA partnering for green energy push

Rio Tinto will conduct a $1.2mn feasibility study, equally funded with ARENA through a $580,000 grant, into using clean hydrogen to replace natural gas in the calcination process of refining at the Yarwun alumina refinery in Gladstone.

The study program includes work to be done at Rio Tinto’s Bundoora Technical Development Centre in Melbourne, where Rio Tinto’s in-house development capability has now been extended to hydrogen.

ARENA CEO Darren Miller commented: “If we can replace fossil fuels with clean hydrogen in the refining process for alumina, this will reduce emissions in the energy and emissions intensive refining stage of the aluminium supply chain. Exploring these new clean energy technologies and methods is a crucial step towards producing green aluminium.

“This study will investigate a potential technology that can contribute to the decarbonisation of the Australian alumina industry. If successful, the technical and commercial lessons from Rio Tinto’s study could lead to the implementation of hydrogen calcination technology, not only in Australia, but also internationally.”

Rio Tinto Aluminium Pacific Operations acting managing director Daniel van der Westhuizen added: “We see the ARENA and Rio Tinto-funded study as a step towards reducing refinery emissions and one that has the potential to play an important part in Rio Tinto’s commitment to decarbonisation.

“We’re investing in work that needs to be done, not only to decarbonise one of our sites, but also to help provide a lower-emissions pathway for Rio Tinto and the global aluminium industry.

“We recognise we are on a long road towards reducing emissions across our operations and there is clearly more work to be done. But projects such as this are an important part of helping us get there.”

Can hydrogen replace natural gas in alumina refineries?

The study comprises two distinct work packages:

  • Preliminary engineering and design study conducted to understand the construction and operational requirements of a potential demonstration project at the Yarwun alumina refinery.
  • Simulating the calcination process using a lab scale reactor at the Bundoora Technical Development Centre.

Once complete, the study will inform the viability of a potential demonstration project. Rio Tinto has lodged patents for the hydrogen calcination process.

Rio Tinto aiming for net zero by 2050

Rio Tinto is aiming to reach net zero emissions across its operations by 2050. Across the company, it is targeting a 15% reduction in absolute emissions and a 30% reduction in emissions intensity by 2030, from a 2018 baseline.

Aluminium is found in everything from cars to phones. But one of the challenges of producing this essential material responsibly is finding ways to decarbonise the process.

Part of the reason is creating alumina – the main ingredient in aluminium – takes a lot of energy, which in turn creates greenhouse gas emissions. New technologies will be essential to helping reduce emissions, but many haven’t been proven. And some not yet even discovered. Rio Tinto's transformation is being driven by innovation and its partnership with ARENA is a positive step towards these goals.
