Maximize Flotation Outcomes by Setting your Desired Targets
.The Flotation Optimizer is a central feature of IntelliSense.io Flotation Optimization Application that allows Operators and Metallurgists to optimize their flotation process in real-time.
Given the feed rate and material properties of ore fed to Flotation, the Flotation Optimizer employs best-in-class modeling methods to generate control setpoints that will maximize the metal recovery at the target product grade.
The Flotation Optimizer performs hundreds of simulations of a Flotation circuit using Digital Process Models (virtual sensors), which determine the solution that best aligns with the ‘Value Driver(s)’ (a configuration of desired objectives set by the users). The optimizer provides ‘Control Variable’ setpoints as ‘Recommended Setpoints’ (RSPs) that can be manually applied by operators or fed directly into lower level Control Systems.
The Flotation Optimizer’s Quest
The Flotation Optimizer addresses a fundamental question:
“What is the optimal way to operate a specific flotation circuit with a given feed to achieve its performance objectives?”
Let’s break down this question to understand the intricacies.
1. What is the optimal way to operate
The Flotation Optimizer isn’t a stabilizing control system; it’s a Scientific-AI optimization system determining the best operating conditions at steady-state based on the feed. It then provides optimal setpoints to operators or directly into lower-level control systems for achieving and maintaining the recommended conditions.
2. A specific flotation circuit
The Flotation Optimizer focuses on optimizing a flotation circuit within the constraints of its existing design, configuration, and instrumentation. We uniquely use Scientific AI – a combination of ‘Physics’ based models with Machine Learning – to cater for mineral processing complexities and drive greater accuracy of predictions.
3. With a given feed
The material properties of the feed ore and the feed rate are considered to be given, outside the scope of the Flotation Optimizer, emphasizing the importance of accurate and recent data for optimal performance. Our ‘Material Handling’ feature allows for the accurate tracking and prediction of ore material properties and their effect on the process in real-time from Stockpile through Flotation and beyond.
4. To achieve its performance objectives
This is dependent on the user-defined Value Driver(s), that outlines the circuit’s goals. The Value Driver(s) includes setting optimizer rewards for ‘Performance Variables’ and limits for ‘Control Variables’. For example, deciding whether to maximize metal recovery or keep the final concentrate metal grade above ‘x’ g/t.
A Practical Industrial Example
In one of our prime AI-driven Flotation projects at one of the world’s largest copper mines in Chile we implemented a Digital Process Model for a circuit with more than 125 cells (totalizing 1,100 hydrodynamic and kinetic virtual sensors) alongside our Flotation Optimizer functionality.
With that, operators and metallurgists can now track flotation process parameters in real-time and pinpoint operational ranges for individual cells that would optimize the entire circuit’s overall performance.
Findings in the rougher circuit showed a significant increase in copper recovery, exceeding 1.1%. This improvement is estimated to positively impact the overall copper recovery of the plant by +1.0% (median), resulting in a $38 million annualized gain.
