Mining and metals businesses exploiting digital twin technology
Within the mining industry, the level of digital twin adoption appeared to be the catalyst in defining the company’s viability and competitiveness. Dozens of businesses work side by side with the processing plant during its lifecycle each contributing to achievement of a certain profit.
Design and Engineering offices
Playing an integral role in deploying and refurbishing an ore processing plant, design and engineering offices leverage digital twin technology to pursue a number of improvements in:
Many companies overcome designing stage challenges by exploiting Building Information Modelling (BIM). Smart and holistic design coupled with the ability to make endless alterations decrease the number of rework and ease visibility and comprehension of the designed asset.
- Clash detection
Avoided miscommunication between departments and the embedded into 3D design software capability to eliminate mistakes early on help to identify inefficiencies before the project is moved on to the next stage.
- Standards compliance
Regulations for mining & metals cover numerous areas of a plant’s lifecycle. Being digitally modelled a plant can ensure smooth permits obtainment and sustainable operation.
- Technicality assurance
Virtual representations covering ins and outs of technological lines, equipment and utilities result in more sophisticated and in-depth outcomes aligned with the project’s targets.
Virtual models created at the design stage encompass static data which finds its use at the next stages of the digital twin deployment.
Engineering, procurement and construction contractors advance digital twin technology to the next level and drive value at the following stages:
3D geometry capture enhanced by BIM technologies creates a laser-sharp model, which is then used to facilitate scheduling and create visualizations, renderings, walkthroughs and animation.
Digital twins become indispensable when it comes to design execution time planning as they foster precise scheduling for further project development, visual validation and installation simulations.
3D virtual replicas built upfront enable quantity and cost calculations to be accomplished in practically no time and with a high level of accuracy. Precise knowledge of what is needed and when allows the prefabrication of certain systems and elements as well as gives detailed expenditure estimations.
To build on time and as designed becomes possible with the digital twin technology implemented to initiate, monitor and inspect the construction process. Digital models give site workers a better understanding of the construction documentation and enable to pinpoint the exact location and materials to be used. Site process tracking mapped on the digital twin shows whether the work is done on schedule and where modifications are needed. As-built vs as-designed comparison identifies discrepancies and speeds up quality assurance followed by building acceptance and plant’s commissioning.
EPC Contractors embrace two areas of the digital twin adoption into an ore processing plant lifecycle enhancing engineering efficiency, minimizing capital expenditures, and accelerating project execution.
Mining & Metals Managing Companies
Mining and metals processing plant operation and management become the next step into digital twin technology adoption. Besides site exploration, project development, CAPEX planning, timely and accurate construction, companies utilize virtual representations of their assets and running processes to ensure their golden age lasts longer. Digital twins of ore processing plants are used for:
- Enhancing efficiency
Exploiting a digital replica of an asset results in opening up a number of insights into operating inefficiencies that lead to deploying new operating models and allow for alternative decisions to be tested in a virtual environment. It also reduces the amount of downtime dispatching predictive maintenance, centralized record tracking and decision making.
- Minimizing operating expenses
Ore processing plant’s energy consumption takes 20% of direct operating costs with transportation costs adding up another weighty lump to overall OPEX. Digital technologies empower management board to excel at optimizing operations and ceasing underutilization of the facility.
- Planning capital expenditures
Long-term capital planning, weighing alternative investment options and selecting the lowest CAPEX scenario in the virtual realm reduce uncertainty of capital expenses choices and enable to commission operations more profoundly.
- Ensuring on-site workers safety
Digital replication of a real-world environment facilitates training process, allowing it to be done remotely and with maximum engagement. Real-time capture of the workers’ activity weaved in the virtual twin ensures safety-measures compliance and boosts crew efficiency.
- Managing risks
In-depth understanding of the asset and its operation, possibility to simulate and test various options increase the facility’s viability through uncertainty. Supply and production chains exposure can be run in a digital twin to quickly recover from unforeseen emergencies and change operations in a way that will correspond to the reconditioned environment.
Virtual replicas deployed at various stages of mining operations empower to explore, design, develop, maintain and manage in a qualitatively new way: centrally, predictively, profoundly, efficiently and without setting foot on the asset’s premises.

Practical advice on what to consider when adopting digital twins in mining
From our experience of implementing digital twins in mining and metals processing plants, there arise a number of issues that need to be tackled in the first instance:
- Set clear goals you want to achieve by leveraging a virtual twin. Setting expectations and defining what problems you want to solve is crucial in delivering value. It’s the value that comes first, not the technology, although the latter must be selected with utmost care. Regarding software, numerous players are on the market with a variety of technological solutions. Such software manufacturers as Autodesk and Bentley Systems are top-notch in providing design, BIM and simulations software but that does not mean they are the only ones to be opted for and other solutions disregarded. A great deal of analysis and estimation should be done upfront with the only thing in mind – that is the clear goal of digital twin technology adoption.
