Lithium is entering a new performance race. According to Global Critical Minerals Outlook 2026 Global lithium demand grew by around 25% annually over the past two years, while global battery demand surpassed 1.5 TWh in 2025, growing more than 35%. Lithium prices have also more than doubled amid stronger energy-storage demand and constrained supply.

As DLE moves toward commercial scale, technology providers are competing on recovery, selectivity, water use, energy efficiency, and processing speed. But in 2026, the benchmark is shifting from technology performance to plant economics and operational resilience.

The question is no longer simply:

“How efficiently can we extract lithium?”

It is:

“How efficiently can the entire plant produce it at commercial scale?”

For producers scaling Direct Lithium Extraction (DLE), recovery alone is no longer enough. Commercial viability depends on balancing recovery, purity, throughput, energy, water, reliability, and cost—and connecting these metrics to operational decisions.

Here are the 10 KPIs lithium processing facilities that should prioritize.

Measure the percentage of lithium captured from feed or brine. Higher recovery improves resource utilization, but the additional energy, reagent, and equipment costs must justify the gain. 

Track lithium concentration and key impurities throughout the process. Higher recovery has limited value if the product requires significant downstream treatment. 

Measure feed processed and lithium produced per hour, day, and year. Tracking throughput across process stages helps identify bottlenecks before they constrain production. 

Track kWh per tonne of LCE across extraction, pumping, separation, purification, and utilities. Correlate energy throughput and operating conditions to identify optimization opportunities. 

Track water intake, recycling, reuse, and losses per tonne of LCE. DOE notes that some geothermal DLE approaches have demonstrated the potential for 99% less water per tonne of lithium than other lithium mining processes. Source: U.S. Department of Energy, Office of Geothermal. 

Measure reagent consumption per tonne of LCE and correlate it with feed chemistry and operating conditions. This can reveal process drifts and opportunities to reduce OPEX. 

Track availability, mean time between failures (MTBF), mean time to repair (MTTR), and unplanned downtime across pumps, membranes, analyzers, controls, and utilities. 

Monitor pH, temperature, pressure, flow, concentration, and impurity levels in real time. During scale-up, small deviations can translate into significant production losses. 

Combine energy, reagents, water, maintenance, labor, utilities, and downtime into one economic view. A high-recovery process is not commercially attractive if its total production cost remains uncompetitive. 

Track CO₂ emissions, energy, water, waste, and other environmental indicators alongside production to connect sustainability with operational performance. 

The next competitive advantage is not simply tracking KPIs—it is connecting them.

A drop in recovery should trigger more than a dashboard alert. Operators need to determine whether the cause is feed variability, equipment degradation, process instability, reagent consumption, or control-system performance—and understand its impact on throughput and cost.

Lithium scale-up is not just an extraction challenge—it is a plant performance challenge.

With global lithium demand projected to grow more than threefold by 2040, getting plant design right is becoming as critical as selecting the right extraction technology.

The most successful lithium facilities understand that long-term recovery, throughput, and profitability are largely determined by early engineering decisions. Hidden design risks may go unnoticed during commissioning, but they can significantly impact plant performance, maintenance costs, and scalability throughout the asset lifecycle.

Why it matters: Accurate brine characterization is the foundation for selecting the right extraction technology and optimizing plant performance.

Why it matters: The best technology is not the newest one, but the one that aligns with the project’s chemistry, production goals, and business objectives.

Impact:

• Reduced throughput
• Higher energy consumption
• Frequent maintenance shutdowns
• Increased operating costs

Why it matters: Early process modeling and regular Plant Health Checks can identify and mitigate these risks before they impact production.

Why it matters: Reliability-focused engineering must consider future expansion, operational flexibility, and maintainability, not just current production targets.

• Equipment degradation
• Process inefficiencies
• Scaling trends
• Energy losses
• Recovery fluctuations

Why it matters: Digital monitoring and predictive analytics enable proactive decision-making, reducing downtime and improving profitability.

• OPEX
• Maintenance costs
• Energy consumption
• Recovery efficiency
• Plant availability

Why it matters: Plants designed for lifecycle performance achieve greater reliability, lower downtime, and stronger long-term returns.

However, the most successful lithium projects recognize that operational excellence begins much earlier. The greatest value is created when engineering decisions made during project development reduce risks before they become operational problems. 

Rather than viewing process engineering, plant design, automation, and digitalization as separate activities, leading organizations are increasingly adopting an integrated lifecycle approach that connects design, operations, and future expansion requirements from day one. 

• Process and plant engineering 
• Feasibility studies and process simulation 
• Equipment, piping, and layout engineering 
• Instrumentation and control design 
• Plant integration and multidisciplinary engineering 
• Brownfield modernization and debottlenecking 
• Process optimization and capacity expansion 

By combining process expertise with plant engineering capabilities, Utthunga helps build lithium facilities that are scalable, reliable, and easier to operate throughout their lifecycle. 

Many of the biggest challenges in lithium extraction originate long before operations begin. Incomplete process understanding, technology integration issues, scaling risks, and reliability gaps can quietly impact plant performance and profitability for years.

Organizations that take a lifecycle-focused engineering approach are better positioned to improve recovery, reduce operational risk, and scale efficiently as lithium demand continues to grow.

South America is at the center of the global lithium supply chain. Argentina and Chile already have operating lithium assets, while new projects and expansions are adding production capacity across the region.

But the next production opportunity may not always require a new mine or a new plant.

Existing assets can often deliver more—if operators know where production is being lost and how to remove those constraints.

As lithium producers face pressure to improve output, recovery, costs, and water efficiency, the focus is shifting from simply building capacity to getting more performance from assets already in operation.

For existing lithium operations, constraints can emerge across the value chain—from brine extraction and wellfield performance to evaporation, processing, utilities, equipment reliability, and downstream conversion. 

The first step is therefore to establish a clear performance baseline. 

Key questions include: 

• Where are production bottlenecks occurring? 
• Which assets are operating below their design potential? 
• Where are recovery losses occurring? 
• Which equipment constraints are limiting throughput? 
• How are feed and operating conditions affecting performance? 
• Where are maintenance issues creating recurring downtime? 

A data-backed assessment can identify the few constraints that have the greatest impact on production. 

For brine-based lithium operations, production performance is closely connected to the relationship between the resource, wellfield, and processing system.

Wellfield behavior can change over time. Brine chemistry, flow rates, lithium concentration, pumping strategies, and reservoir conditions can all influence production.

Optimization therefore needs to look beyond individual assets.

Resource behavior → Wellfield performance → Process recovery → Production output

Connecting these variables can help operators identify opportunities to improve extraction and processing without simply adding more infrastructure.

Expansion is not always the fastest route to higher production.

Existing plants may contain underutilized equipment or hidden constraints that prevent the operation from reaching its full potential. Utilities, material flows, instrumentation, control loops, equipment availability, and process interfaces can all become bottlenecks.

A structured debottlenecking exercise can help identify where targeted engineering changes can unlock additional capacity.

This could involve:

Process optimization | Equipment upgrades | Control improvements | Utility optimization | Automation enhancements | Maintenance improvements

The objective is to increase throughput while minimizing unnecessary capital expenditure.

Most operating lithium assets generate significant volumes of process and equipment data. The challenge is turning that data into decisions.

Industrial connectivity can bring data from field devices, control systems, equipment, and production systems into a common operational view.

Advanced analytics can then help identify process deviations, equipment degradation, abnormal operating conditions, and production losses.

Digital twins can support what-if analysis and help teams evaluate process changes before implementing them in the plant.

AI can take this further by helping identify patterns that may not be immediately visible through conventional monitoring.

The goal is not more data. It is better production decisions.

Utthunga can help South American lithium producers connect process engineering, automation, industrial connectivity, and digital intelligence to improve existing asset performance.

Its capabilities can support:

• Process & Plant Engineering – identify constraints and optimize plant performance.
• Automation & Controls – improve control strategies and process stability.
• Industrial Connectivity – connect equipment, control systems, and operational data.
• Digital Twin & Simulation – evaluate optimization scenarios before implementation.
• AI & Analytics – identify production losses, anomalies, and reliability opportunities.
• Asset Reliability – improve equipment availability and maintenance effectiveness.

This approach is particularly relevant as regional producers pursue phased expansions and seek to leverage existing infrastructure rather than treating every production increase as a greenfield development. Recent expansion plans in Argentina demonstrate this direction, including phased capacity additions designed to leverage existing infrastructure and operating experience.

Brazil is emerging as an important lithium-producing region, with growing activity around resource development, processing, and battery-material supply chains. But moving from a promising resource to sustained commercial production requires more than securing reserves or proving a process.

For Brazilian lithium producers, the next challenge is speeding up the transition from resource potential to reliable, scalable production.

That requires engineering decisions to be made early, integration to happen across disciplines, and operational readiness to be built into the project from the start.

No two lithium resources behave exactly the same way. Mineralogy, grade, impurities, recovery characteristics, and feed variability can all influence process performance.

For hard-rock lithium projects, this can affect crushing, beneficiation, concentration, conversion, material handling, water, and energy requirements. For projects exploring Direct Lithium Extraction (DLE), feed chemistry, pretreatment, water management, chemical requirements, and downstream processing introduce additional considerations.

The first step toward faster commercialization is therefore a resource-specific process and engineering strategy.

The objective should not simply be to prove that lithium can be extracted. It should be to establish a process that can be engineered, integrated, controlled, and scaled economically.

One of the biggest risks in lithium projects is the transition from pilot-scale success to commercial-scale performance.

A pilot can demonstrate technical feasibility, but commercial production introduces new challenges around equipment sizing, process integration, utilities, automation, controls, material flows, and operating conditions.

Producers can reduce this gap by bringing plant engineering into the process-development stage.

Early engineering can help identify:

• Process integration requirements
• Equipment and utility requirements
• Control and instrumentation needs
• Bottlenecks and operational constraints
• Data and connectivity requirements
• Commissioning and ramp-up priorities

This creates a clearer path from pilot validation to execution-ready plant design.

Commercial readiness should not begin when the plant is ready to start.

Operational requirements need to be considered during engineering.

Control philosophy, instrumentation, asset hierarchy, alarm management, maintenance strategy, operator workflows, production KPIs, and data architecture should be defined before commissioning.

This allows teams to identify operational issues earlier and reduces the risk of discovering critical gaps after startup.

The goal is simple:

Build a plant that is ready to operate—not just ready to commission.

Another important acceleration opportunity is looking beyond the primary lithium extraction or processing technology.

Commercial production depends on the interaction between multiple systems:

Process → Utilities → Equipment → Automation → Controls → Data → Operations

For DLE projects, for example, the technology package needs to integrate with pretreatment, utilities, downstream processing, instrumentation, automation, and plant-wide digital systems.

A fragmented approach can create interfaces, delays, and integration risks. A coordinated engineering approach can help identify these dependencies earlier and support smoother execution.

Utthunga supports lithium producers and technology providers across the engineering and digital layers required to move from process development toward commercial operations. 

Its capabilities include: 

• Process & Plant Engineering – translating process requirements into execution-ready engineering.
