Mining ExpertiseApplied
Minpraxis combines mining and mineral-processing experience with data-driven analysis to help operators improve comminution circuits, evaluate technologies and reduce energy use.
Our work spans early-stage evaluation, testing, analysis and implementation, helping mining teams make better-informed engineering decisions.
Energy conservation
Use Less Energy.Get More From Your Circuit.
Crushing and grinding are major energy consumers in mining operations. Minpraxis helps operators understand where energy is being used and identify opportunities to improve the performance and efficiency of their comminution circuits.
Work can extend from energy-efficiency studies and benchmarking through technology evaluation and implementation.
Services include
- Energy-efficiency studies
- Energy baselining and benchmarking
- Alternative flowsheet and technology evaluation
- Mill surveying and performance analysis
- Crushing and grinding circuit analysis
- Energy-conservation implementation
Supports
- Energy Reduction
- Circuit Optimization
- Technology Evaluation
- Operating Performance
- Lower-Carbon Electrification
