Direct Lithium Extraction (DLE) is gaining momentum as lithium producers look for faster and more efficient ways to recover lithium from brines. But deploying DLE technology does not automatically mean a facility is achieving its full recovery potential.
Recovery can be affected by brine variability, pretreatment, process conditions, equipment performance, and operational controls.
Here are five warning signs that your DLE facility may be leaving recovery—and production value—on the table.
1. Recovery Changes With Feed Conditions
If recovery changes significantly with feed conditions, the process may not be optimized for the actual brine entering the plant.
Watch for:
- Variable lithium concentration
- Changing impurity levels
- Unstable flow or temperature
- Recovery fluctuations without a clear cause
Understanding the relationship between brine characteristics and recovery is the first step toward improving performance.
2. Pretreatment Is Affecting DLE Performance
DLE performance starts before the extraction stage.
Solids, scaling compounds, organic matter, and other impurities can affect extraction media, membranes, solvents, and downstream equipment.
Signs of a pretreatment problem include:
- Increasing fouling
- Frequent cleaning
- Pressure fluctuations
- Rising chemical consumption
- Declining extraction performance
A stable pretreatment process creates the conditions for more consistent DLE recovery.
The extraction stage can only perform as well as the feed preparation allows.
3. Extraction and Regeneration Cycles Are Inefficient
DLE systems typically involve multiple cycles, including extraction, regeneration, washing, and lithium recovery.
Small inefficiencies can accumulate into significant production losses.
Long cycle times can reduce throughput, while incomplete regeneration can reduce extraction capacity in subsequent cycles.
Operators should continuously monitor:
Cycle time | Extraction efficiency | Regeneration performance | Lithium concentration | Chemical consumption
The objective should be to optimize the complete operating cycle, not just one process parameter.
4. You Have Data but Not Enough Operational Insight
DLE facilities can generate large volumes of process and equipment data. But more data does not automatically mean better recovery.
If operators cannot connect changes in flow, pressure, chemistry, temperature, equipment condition, and recovery, important optimization opportunities can remain hidden.
Industrial connectivity and analytics can help identify:
- Recovery deviations
- Process instability
- Equipment degradation
- Abnormal operating conditions
- Emerging bottlenecks
Digital twins can also help evaluate process changes before they are introduced into the operating plant.
The goal is not more data. It is better recovery decisions.
5. You Know Recovery Is Falling—but Not Where
A recovery percentage tells you what happened. It does not necessarily tell you where the loss occurred.
A stronger approach is to track lithium across the complete process:
Brine Feed → Pretreatment → DLE → Regeneration → Concentration → Product Recovery
This can reveal where lithium is being lost and which process stage offers the greatest opportunity for improvement.
Instead of optimizing individual equipment, producers can then focus on end-to-end recovery performance.
How Utthunga Can Help
Utthunga helps DLE technology providers and lithium producers connect process engineering, automation, industrial connectivity, and digital intelligence to improve plant performance.
Its capabilities include:
- Process & Plant Engineering – identify constraints and recovery losses.
- Automation & Controls – improve process stability and control.
- Industrial Connectivity – connect equipment, control systems, and operational data.
- Digital Twin & Simulation – evaluate optimization scenarios.
- AI & Analytics – identify process deviations and performance patterns.
- Commissioning & Optimization – support the transition from pilot to stable operations.
For DLE facilities, improving recovery is not about optimizing one number in isolation. It requires understanding how brine quality, pretreatment, extraction, regeneration, downstream processing, equipment, and controls work together.
Recover More From the Process You Already Have
DLE’s commercial value depends on consistent performance under real operating conditions.
If recovery fluctuates, pretreatment becomes unstable, cycles take longer than expected, operational data remains disconnected, or lithium losses cannot be traced, valuable production may be left on the table.
The question is:
Are you measuring recovery—or actively engineering it?
By connecting engineering, automation, data, and continuous optimization, DLE operators can move toward higher recovery, more predictable production, and stronger commercial performance.
