PROCESS CONTROL

Mining is full of uncertainties and variance . indurad argues that while these cannot be eliminated – they can be significantly managed and mitigated . The indurad technology is focusing on this stack . “ Our iCrusher allows the identification of oversize , our iStockpile5D allows monitoring and homogenisation of product quality and reduction of segregation . The maritime industry has been pioneering in the use of radar for adverse environmental conditions – indurad brought this success to mining allowing machine vision under dust , water suppression , fog and snow . iApron and iBelt allow reduction of spillage and avoidance of blocked chutes as well as lifetime extension of feeders . Finally , teleremote operation and full automation with iStacker and iReclaimer allow management of the human factor .”
Sam Walsh , the former CEO of Rio Tinto has been bringing the Six Sigma approach into mining . His guiding principle has been ‘ there will be latent capacity there .’ At at recent St Barbara lunch of the Western Australian Mining Club he emphasised : “ There will the things that don ’ t run smoothly . You can work through with focus . So there is variation in mining . And there is an opportunity to apply the discipline of Six Sigma to mining .”
When loading wagons with iron ore there is significant variation in the outload process , both by tonnes per car and by loading time . indurad iLoadout has been proven to add one tonne more ore per car , while reducing the number of overloads at the same time , resulting as well in more energy efficient haulage and compliant trains plus mitigating the risk of bogie-bias and derailment risk . indurad applies radar machine vision to target the reduction of variation with end-to-end from mine-to-market , split in two value chains . The ‘ mine-plant-product ’ process is present at all mining operations , whereby indurad is focusing on the dry process plant of large copper , gold , bauxite , salt , iron ore and coal operations , however , also at smaller operations focusing on critical minerals like nickel and lithium . The rail outload process is very focused on iron ore , salt and coal . The nature of a connected system eliminating downtime and adding productivity during uptime typically results in double digit value opportunities .
Digital twins at Quellaveco
Anglo American says it has implemented cuttingedge technology at the Quellaveco copper mine in Peru with which it is possible to create a virtual replica that simulates everything that happens in its process plant , and with this , digital mining specialists can carry out predictive tests that help reduce security risks , optimise the use of resources and improve the performance of production teams .
The digital twins allow virtual replicas of the equipment and infrastructure to be made , displaying information on technical characteristics and operation utilising IoT , with the same data as that provided by the sensors installed in the mine . The digital twins are controlled from the Integrated Operations Center ( CIO ), which is the brain of Quellaveco . There are twins of the grinding system , flotation , tailings management , water control , electrical system , among others . These are

learning and provide recommendations to avoid failures in the equipment or real processes , optimising costs and time , through simulations of the different processes , using artificial intelligence ( AI ).
“ Digital twins not only allow us to have better performance , but they increase safety by reducing error rates , which means a new standard of efficiency in the mining industry ,” says Cinthya Lozano , Superintendent of the Integrated Operations Center of Anglo American . “ For example , we can place a parameter in a pump and see how it behaves . If it doesn ’ t work properly , we change these parameters as many times as necessary , and when we have the correct data we just take it to the real world ,” she adds .
Quellaveco is one of the first mines to implement digital twin technology to improve efficiency and safety in its mineral processing plant , taking advantage of the connectivity and sensorisation that have made it the first 100 % digital mine in Peru .
Underpinning the Anglo American Quellaveco digital twin is the COMOS platform from Siemens which integrates Siemens ’ own process control system Simatic PCS-7 , which for example controls the gearless driven conveyors and grinding circuit , together with other systems . The integrated COMOS software solution makes it possible to consolidate automation data from the control systems of different providers .
Siemens states : “ It guarantees the optimal collaboration , continuity , and consistency of all the disciplines involved in plant engineering and operation . The system accomplishes this by consolidating a variety of sources . Using the automation digital twin of the COMOS software solution , automation data can be read out of the process control system and imported to COMOS to be graphically displayed , consolidated , and made available for further engineering . COMOS uses this data to support the creation of the plant ’ s digital twin , a fast and reliable migration , and updates to the process control system – all with one single solution .”
