Bartram comes back to TOMRA Mining ready for sensor-based sorting demand uptick

Having left TOMRA Mining more than a decade ago only to return to the Germany-based company in November, Kai Bartram’s re-arrival at the sensor-based sorting firm represents a good time to take stock and reflect on how far the mining sector has come with its understanding and acceptance of this type of pre-concentration technology.

Bartram, now Global Sales Director of TOMRA Mining and a member of TOMRA’s Mining Management Team, was happy to answer some of IM’s questions after getting his feet back under the table in the company’s offices in Wedel, Germany.

IM: How has the mining industry’s appreciation of the benefits of sensor-based ore sorting changed since you left TOMRA in 2010? What trends have led to a wider take up of the technology?

KB: In 2010, sensor-based sorting (SBS) was still seen as a niche technology in the mining industry. Some smaller, more innovative mining companies had seen the potential and effectively implemented SBS, but the mining industry, as such, had not accepted the technology. While in the industrial minerals sector several optical sorters – and, in the diamond industry, mainly X-ray luminescence machines – were operating, the rest of the industry was cautious about integrating sorters into their flowsheets.

That changed slowly with the introduction of Dual Energy X-ray technology. The technology is so robust and perfectly suited to the harsh environment of the mining industry that the economic benefits of pre-concentration became obvious. Another point that has strongly supported the adoption of sorting technology is the fact that average ore grades keep decreasing while energy costs keep increasing.

IM: Diamond and industrial mineral operations were typically the first adopters in the mining sector; what commodity sectors do you expect to see dominate demand for sensor-based ore sorting systems into 2030? What changes to the technology or wider industry understanding have led to this belief?

KB: In the beginning, sorters were seen as small machines, which would never meet the capacity requirements of large hard-rock mineral processing circuits. Therefore, only small mines saw the opportunity to implement sorting as a pre-concentration step in their process. Today, we see that our 2.4-m-wide flagship sorter, TOMRA COM XRT 2.0, can process up to 500 t/h, so that large operations can also implement the technology. An example of such a trend is the Ma’aden Phosphate Umm Wu’al processing plant, where 2,000 t/h are processed with TOMRA XRT sorters.

I am sure we will see more of these bigger projects in many different commodities. Of course, the current market trend is towards ores that are required for the electric revolution, like lithium, copper, cobalt and rare earth elements. TOMRA has proven that we have the right solution to upgrade those ores efficiently and can contribute to more economical output. So, I expect to see more installations in the future.

IM: Are there any regions more willing to apply these solutions than others? Why is this the case?

KB: If you look at our global reference list, you can see that the larger installed base resides in Europe, Africa and the Americas. The Asian markets are a little behind, but this is easily explained by history. As a European company, we focused more on the better known and established markets. In general, the mining market is a very global industry with big players active in all continents.
I do not believe there are regions more willing to apply the technology than others. It is just a matter of supporting all regions in the same way. TOMRA is investing heavily to ensure we have a good global support network, to be there for and with our clients.

IM: Do you expect to see more collaboration with OEMs over the next decade when it comes to implementing ore sorting solutions with process flowsheets? How do you see the input of both TOMRA and OEMs benefitting the wider mining industry?

KB: Collaboration is essential in any industry. We need specialists who are experts in their field, and TOMRA is one of the global leaders in sensor-based sorting. In order to achieve the best results in one field, one must focus. Therefore, big projects can only be undertaken by a group of companies or experts who collaboratively work together. We, as a solution provider, are very dependent on well-engineered and integrated plant designs and believe we have to collaborate and have close relationships with plant builders to ensure the best possible solution for our clients.

Evaluate ore sorting options at prefeasibility study stage, TOMRA’s Rutledge says

TOMRA Mining is making a case for its sensor-based ore sorting solutions to be evaluated earlier in the mining project evaluation phase, with Jordan Rutledge, Area Sales Manager, arguing that consideration of its use at the very beginning of flowsheet discussions can influence up- and down-stream equipment selection.

The company’s sensor-based ore sorting systems have spread across the mining sector, migrating from industrial minerals and diamond operations to base and precious metals.

Speaking at a sensor-based sorting seminar in Toronto, Canada, held late last month, Rutledge (pictured) said the use of the technology needed to be considered early in the mine development scope in order to leverage the most benefit for the operation.

“Sensor-based sorting should be considered in the flowsheet from the beginning and evaluated in prefeasibility studies to see if it is suitable for the project and will add value to the plant,” she said.

“In many cases, sorting works really well and, as we continue to go towards a green economy, the use of our resources is vitally important. In order to make the best use of them, sorting plays a critical role.”

Rutledge, an event organiser and presenter, joined 40 participants from across Canada at the seminar, which included representatives from miners such as Agnico Eagle, Capstone Mining and Cheetah Resources; from laboratories such as testing and certification company SGS and the Saskatchewan Research Council ; from engineering companies such as DRA Global, Primero, CIMA and Halyard; and students from the University of Toronto.

“The event highlighted the important role of sensor-based sorting technologies in green mining and their potential to unlock significant value in mining projects, as well as the possibilities of digitalisation for supporting customers and managing connected equipment,” TOMRA said.

TOMRA connects ore sorters to the cloud with TOMRA Insight

After a successful launch in its recycling division, TOMRA is rolling out its cloud-based data platform, TOMRA Insight, to mining customers.

TOMRA Insight enables sorting machine users to improve operational efficiencies through a subscription-based service that turns these machines into connected devices for the generation of valuable process data.

Following a successful launch last year by TOMRA Sorting Recycling, TOMRA is now also being made available to customers of TOMRA Mining and TOMRA Food. For all three industries, the platform is enhanced by new features and functionalities that make TOMRA Insight even more valuable than when it was launched to recyclers in March 2019.

The data from TOMRA Insight is gathered in near real time, stored securely in the cloud, and can be accessed from anywhere and across plants via a web portal available for desktop and mobile devices, according to the company.

Felix Flemming, Vice President and Head of Digital at TOMRA Sorting, said: “By capturing and using valuable data, TOMRA Insight is transforming sorting from an operational process into a strategic management tool. This tool is constantly becoming more powerful as we continuously develop it in response to customers’ needs and priorities. New functionalities and features are released every three weeks – a routine during which TOMRA works closely with customers in pursuit of shared objectives.”

Data captured by TOMRA Insight provides valuable performance metrics that help businesses optimise machine performance.

Operating costs are reduced by simplifying spare part ordering and offering flexible access to data and documentation, according to the company. Downtime is reduced by monitoring machine health and performance in near real time, identifying gaps in production and analysing potential root causes. This allows management to move to predictive and condition-based maintenance, preventing unscheduled machine shutdowns.

Throughput, meanwhile, is maximised by evaluating variations and optimising sorting equipment, accordingly. Sorting to target quality is enhanced by having accurate material composition data to enable decisions to be based on more detailed information.

For the mining and mineral processing industries, TOMRA Insight’s ability to collect detailed data from TOMRA’s sorting machines means that previously hidden information can lead to improvements in efficiencies and profitability.

Data captured by TOMRA Insight is analysed on behalf of customers by TOMRA Mining engineers, and key findings shared in confidential reports supplied to customers on a monthly basis. This arrangement has the advantage of combining objective statistical analysis with the interpretive skills of a service team familiar with the customer’s unique challenges, TOMRA says.

“TOMRA Insight’s data-gathering helps mineral processors in near real time and in retrospect,” the company said. “Machine operators are empowered to take prompt action in response to changes in material composition on the line and managers are empowered to make operational and business decisions based on more complete information.”

Comparisons between multiple sites or lines can now be made more accurately and difficult-to-reach processing operations can be remotely monitored from more convenient locations, the company said. This functionality is especially useful in the face of widespread travel restrictions related to COVID-19.

One early, pre-launch user of TOMRA Insight is the Black chrome mine in South Africa (pictured above), one of two mining projects that form the basis of the Sail Group’s plans for long-term sustainable chrome production. Since TOMRA Insight was connected to sorting machines here at the start of 2020, the data platform has convincingly proven its effectiveness, TOMRA said. Among the gains made so far are improvements in process monitoring and streamlining, more efficient line-feeding and machine running times, and reduced downtime.

Albert du Preez, Senior Vice President and Head of TOMRA Mining, said: “By accessing information, TOMRA Insight is unlocking new opportunities. Mineral processors can now move from making decisions based on experience and local observations to decisions based on experience and hard facts. This means TOMRA Insight can help reduce waste rock and downstream processing costs, enabling processors to earn more dollars per tonne.”

To build on these benefits, TOMRA Mining is working closely with customers to continuously develop TOMRA Insight. The future will bring the addition of more features and functionalities, which customers will automatically receive as part of their Service Level Agreement.

TOMRA takes XRT ore sorting testing virtual in face of COVID-19 restrictions

TOMRA Sorting Mining is bringing ore sorting testing capabilities to its stay-at-home mining customers though the development of virtual testing facilities that enable them to take informed purchasing decisions for their processing plants, regardless of location.

This is the latest action in the company’s plan to provide its customers the support they need to take their business forward in the face of current COVID-19-related restrictions.

“Ensuring business continuity at this time is of paramount importance for mining operations,” TOMRA Mining said. “This includes taking forward ongoing investment projects in sorting equipment to improve their efficiency and the quality of their product.”

TOMRA Mining is leveraging digital technology to help customers identify the best sorting solution for their mine by offering them remote access to its Test Center in Wedel, Germany, a facility that has capabilities for all applications, according to the company.

“TOMRA’s temporary Virtual Demonstration and Test Solution will enable mining companies to test the sorting solutions on their samples without leaving their office,” the company said. “They will just need to book a session with their TOMRA sales representative and ship a sample of their minerals to the Test Center, which will conduct the test.”

Once testing is complete, mining customers will receive a video of their material being sorted and be able to discuss the results with a TOMRA sales person and the Test Center’s experts via video call, the company said. “With their support, they will be able to make a decision on the following steps and take the project forward without delay,” it added.

Albert du Preez (pictured), Senior Vice President and Head of TOMRA Sorting Mining, said: “At TOMRA, we work closely with our customers to devise the solution that is perfect for their operation. The visit to one of our test centres can be an important step in this process, as it enables them to work out with our teams the best combination of technologies and develop the flowsheet for their ore sorting plant.

“With this virtual solution, we are able to provide this support, taking our Test Center to our customers’ office so they can make an informed decision on an important investment. This means that they are able to take their business forward in the current situation.”

TOMRA’s test centres play a key role in the company’s collaborative approach to supporting customers with their ore sorting requirements, according to the company. Based on the tests conducted on TOMRA equipment with material from the customer’s mine, the centre can provide an initial feasibility study and detailed reports on the machine’s performance with the sample. With this information and the advice of the centre’s experts, the customer can proceed with their investment with confidence, the company says.

The opportunity for the customer to see first-hand the equipment at work on their sample and discuss the options with TOMRA’s team provides important added value, according to the company.

This was the experience of John Armstrong, VP Mineral Resources at Lucara Diamonds, who visited the Test Center in Wedel when researching a solution for the diamond mine in Karowe, Botswana.

“We gained a lot of confidence in the people at TOMRA, in the technology that they were presenting to us, and the possible solution that it provided to the Karowe mine…We could also see that they had already gone down the road of the next step in X-ray Transmission (XRT) technology, so they were not just focused on one particular module to present to us, but they were working on different modules.

“That helped alleviate some of our concerns about the robustness of the platform and the technology itself, which ultimately led us to use TOMRA as the solution.”

Lucara has since gone on to recover some of the largest diamonds in history with the TOMRA XRT system that was installed following this visit to the Test Center.

In addition to developing this Virtual and Demonstration and Test Solution in reaction to the COVID-19 outbreak, TOMRA has increased stocks of critical components to ensure its ability to fulfil current and future orders, and to ensure the supply of spare parts without disruption.

And the company is leveraging digital technology not only to take the expertise of its test centres to customers, but also by using its remote service and training tools to support their equipment while respecting social distancing safety measures, it said.
