The hydrometallurgical processing circuit is designed to recover battery specific metals (cobalt, nickel lithium, and manganese) as well as residual electrode materials (copper and aluminium) in various forms from spent lithium-ion batteries.
Neometals has recognised the rapidly growing requirement to recycle lithium-ion batteries and the company is progressing the commercialisation of its proprietary process for recovering cobalt and other valuable materials from spent lithium-ion batteries.
Primero were engaged to assist with the flowsheet development for the process and subsequently design, build and commission a battery recycling pilot plant at the client’s facilities in Montreal, Canada.
Extensive battery metals experience coupled with offices in both Perth and Montreal meant that Primero were well positioned to execute the following for Neometals
- Develop and conduct bench-scale tests for various stages of the battery recycling pilot plant process.
- Create engineering design documentation and deliverables to an as-built status.
- Commission the battery recycling feed preparation pilot plant
- Review all external hydrometallurgical bench-scale and pilot plant testwork and incorporate data into an overarching process design.
- Carry out scoping studies for a full-scale commercial plant.
The battery recycling pilot plant utilises a mechanical separation circuit to produce an upgraded product suitable as feed material to the hydrometallurgical processing circuit. The hydrometallurgical processing circuit is designed to recover battery specific metals (cobalt, nickel lithium, and manganese) as well as residual electrode materials (copper and aluminium) in various forms from spent lithium-Ion batteries.
A FEED study is planned to follow the pilot and precede an economic feasibility study to give Neometals a commercial handle on approximately 80% of costs at an early development stage.
