INTEGRATED TECHNICAL APPROACH
Complex Lithium Projects Require More Than Standard Engineering
Lithium projects involve complex interactions between resource chemistry, process design, recovery, water, energy, environmental constraints and project economics. PEC helps clients connect these variables into an integrated technical approach.
01
Process Complexity
Understand the chemistry and process requirements before major investment decisions.
02
Technical Risk
Identify bottlenecks, process limitations and scalability risks early.
03
Project Value
Develop solutions that balance recovery, operating costs, capital requirements and environmental considerations.
Lithium Processing Expertise
Process solutions adapted to the chemistry, resource and objectives of each project.
DLE Technology
Direct Lithium Extraction and related process integration.
Solar Evaporation
Process development for conventional evaporation-based lithium production.
Spodumene
Processing and conversion routes for hard-rock lithium resources.
Clay & Sedimentary Resources
Process development for alternative lithium-bearing resources.
Refining Technologies
Concentration, crystallization and purification technologies.
Battery-Grade Lithium Chemicals
Process development for high-purity lithium carbonate and lithium hydroxide.
EXECUTION PHASES
From Concept To Operation
Delivering comprehensive technical continuity across every milestone of lithium project maturation.
01
Development
Conceptual engineering, scoping, PEA, PFS and feasibility support.
02
Construction
Technical support and engineering coordination during project execution.
03
Commissioning & Start-Up
Support to accelerate commissioning and reduce the operational learning curve.
04
Operation
Process optimization, troubleshooting and technical consulting.
Technical Support Across The Project Lifecycle
Specialized capabilities tailored to the engineering and operational challenges of lithium projects.
Process Development
Bench and pilot-scale process modeling, simulation, and flowsheet optimization.
Process and Project Development
End-to-end technical coordination between metallurgical tests, plant layout, and execution.
Start-Up
On-site technical support to de-risk plant commissioning and ramp-up production schedules.
Consultancy
Targeted advisory on bottleneck elimination, reagent consumption, and mass-energy balances.
Financial Analysis
Robust OPEX and CAPEX benchmarking linked directly to physical chemical processing realities.
Environmental Assessment
Water stewardship, reinjection mechanics, and sustainable byproduct management strategies.
Qualified Person
Certified NI 43-101 and JORC compliance sign-offs on mineral processing and extraction.
