SourcesHow do you separate something valuable from a complex liquid?

How it works
Schematic · not to scale
From mixture to material
Mixed brine contains lithium alongside other substances.
Separation recovers a lithium-rich stream.
Purify and convert toward battery-grade material.
Manage the remaining material in a separate stream.
The return arrow shows test results informing design. Compare recovery, purity, water and energy. The dots represent a conceptual mixture, not particular chemical species or measured amounts.
The lesson, in the real world
A separation has to recover the useful material, reach the right purity and work beyond a small test.
Project stage: Development and scale-up. The planned commercial facility is not operating yet.
- 1
E3’s Clearwater project targets lithium dissolved in underground brine in Alberta.
- 2
Extraction and downstream treatment separate and purify the material. E3’s process role names membrane treatment, ion exchange and crystallization among the methods it evaluates.
- 3
Engineers and operators use models, operating readings and demonstration tests to inform equipment and process design.
- 4
Compare recovery and purity alongside water, energy and reliable operation. A demonstration result does not by itself show that a commercial plant is operating.
Our explanation
Who does this work
Role
Process engineering
Design and test the steps that separate useful materials from a mixture.
Process engineers connect chemistry to equipment and operating conditions. They use calculations, models and test results to decide how a process should work, then help troubleshoot what happens when it is scaled up.
What might you actually do?
Compare separation steps
Evaluate how different treatment stages affect recovery, purity and resource use.
Check the balances
Account for material entering and leaving each stage, using models and measurements.
Test and improve
Use pilot or demonstration results to improve designs and support commissioning.
Typical of this kind of work in general. Not a description of any one person’s job at E3 Lithium.
- Often works with
- Plant operatorsLaboratory staffEquipment suppliersOther engineers
- Classroom connection
- Concentration, mixtures and quantitative chemical change become practical questions about recovery, purity, water use and scale.

About this route
An undergraduate engineering route. The Stantec job example asks for a relevant degree and EIT registration or eligibility; E3’s role additionally asks for substantial experience.
Why it connects to the work · our interpretation
Process engineeringDesigning and evaluating chemical processes provides a foundation for separation, water treatment and scale-up work.
SAITTwo-year diplomaCalgary
Chemical Engineering Technology
Practical work in unit operations, process simulation, equipment design and safe operation of processing units.
About this route
A technology diploma is a distinct route from an engineering degree; it does not replace a posting’s engineering-degree requirement.
Why it connects to the work · our interpretation
Process engineeringProcess calculations and simulation support technical work alongside engineers.

Ask the class
If two separation methods recover different amounts of lithium but use different amounts of water and energy, what would you need to compare before choosing one?
Separating a useful substance is only part of the challenge. A process also has to work repeatedly, at a useful scale, with acceptable resource use and cost.
Mindset it shows
Optimize across competing constraints rather than one number.
About E3 Lithium
Developing a route from Alberta brine to battery-grade lithium carbonate.
- Local connection
- Clearwater lies between Calgary and Red Deer. The operator job example is for the demonstration facility east of Olds and Didsbury; the engineering posting is based in Calgary.

- Team size
- Not verified. We have not found a dated, sourced figure.
- The problem
- Lithium is dissolved in underground brine alongside other substances. Producing a battery material requires extraction, purification and conversion, with a process that can work at larger scale.

- What they do
- A planned supply of battery-grade lithium carbonate from Alberta brine. This is a development project, not an operating commercial plant.
