Digital twin models offer “transformative” opportunities for resource engineering

Last year PETRA recently ran a series of webinars on mine value chain optimisation using digital twin models.

The webinars focused on digital twin models for geometallurgy, materials handling performance and drill & blast optimisation. Industry experts and academics joined CEO Dr Penny Stewart for a panel discussion about data quality and implementation of digital twin models.

Dr Alan Alan Tordoir, Drill & Blast lead at AngloAmerican and Dr Sarma Kanchibotla, Director at Seshat Consulting joined PETRA CEO, Dr Penny Stewart from PETRA.

Before the panel discussion Dr Penny Stewart presented a short demonstration and case study on MAXTAGeomet and MAXTADrill&Blast. MAXTA digital twin models use data from the entire value chain to learn how geology affects downstream processes, creating a new paradigm for prediction, simulation and optimisation of blasting, loading, crushing, grinding and recovery.

“I think that (that), is one of the most transformational aspects of all of this work for mining companies”

-Dr Carmen Letton Head of Resource Development Planning and Life of Asset Planning At Anglo America, speaking on how MAXTA Digital twin modelling allows you to look at the combinations for ore as they arrive at any point in the value chain (36:00 of webinar recording Geomet 2)
