Overview
Spodumene concentrate is produced by crushing, dense-medium separation and flotation, and is the dominant industrial feedstock for hard-rock lithium. SC6.0 grades are typically converted to lithium carbonate or hydroxide via the sulfate or alkaline route, while low-iron grades go directly to glass, ceramics and glass-ceramics.
- Li₂O 5.5–6.5% across multiple grades
- Fe₂O₃ controllable below 1.0%
- Bulk bags, bulk containers and custom particle size

Referenced to YS/T 261 and company standards; grade and impurity limits can be agreed to suit the conversion kiln or flotation circuit.
Reference standards
Standards and values are typical references. Supply is governed by the agreed technical protocol and the batch COA.
Main applications
Packaging and storage
Packaging
1 t bulk bags or bulk containers; inner liners available on request.
Storage
Keep dry and segregate to prevent cross-contamination; avoid co-stacking with alkaline materials such as limestone.
