OreMet Optimizer

OreMet Optimizer for mining value chain analysis

- Ongoing


Geometallurgical modelling and simulation tool: The OreMet Optimizer provides an innovative holistic approach to optimizing the value chain from mine to mill.


OreMet Optimizer is a software innovation developed by Outotec that uses the company’s process simulator as the backbone for conducting geometallurgical studies. The product allows optimization of the processing routes for variations of the ore properties, leading to improved resource efficiency and increased operating profit. It can also be a valuable tool in environmental impact assessment. The OreMet Optimizer provides an innovative holistic approach, geometallurgy, to optimizing the value chain from mine to mill. 
Geometallurgy is a young cross-discipline that combines geological information of the ore with mineral processing properties in one spatial deposit model. The deposit model is subsequently used as the input to the numerical process model that describes the mineral processing flowsheet. Such an integrated and multi-disciplinary approach requires resource characterisation by process mineralogy, particle-based modelling and simulation, as well as an economic evaluation. While individual concepts have been known for a while, the integrated geometallurgy approach, as it is known today, became established during the early 2000s. In the beginning, development was dominated by Australian, South African and North American researcher groups. Since 2010, European institutions are also a part of that.
Since then, several concepts and methods have been developed and are partly established as services (consulting companies) or as implemented in the business processes of mining companies and mine project developers. Outotec launched the OreMet Optimizer in 2017.
