Lithium Refining for
Hard Rock Li Producers
Refine hard rock Li

Hard rocks such as spodumene and lepidolite are common sources of lithium. Incumbent processes for refining battery-grade lithium from hard rock are capital intensive and produce sodium sulfate waste that requires costly and proper disposal. Mangrove optimizes the refining process of lithium sulfate from hard rock to lithium hydroxide using ground-breaking electrochemical technology resulting in unparalleled purity and eliminating the challenges and costs of waste disposal.
Conventional lithium refining vs Mangrove's lithium refining for hard rock Li producers
The benefits of Mangrove's game-changing refining technology for hard rock producers
- Eliminates sulfuric acid consumable cost through recycling of by-product
- Eliminates the need for caustic sodium hydroxide consumable
- Eliminates the challenges and costs of disposal for sodium sulfate
- Can co-locate and refine near the point of lithium extraction
- Unlocks previously unviable feedstocks for cost-effective battery-grade refining
- Modular technology can be scaled to meet capacity and meet product specifications
- Achieves high purity battery-grade lithium hydroxide
The challenges with traditional lithium conversion from hard rock
- Time and capital intensive
- Widely available hard rock acids are not cost-effective to refine to battery-grade
- Requires additional costly chemical inputs
- Produces sodium sulfate waste that needs to be properly disposed of
- With incumbent technology, lithium sulfate is frequently shipped overseas to refining partners, exposing stock to supply chain risks and associated costs
