Spodumene processing
Extracting lithium from spodumene involves more than achieving high recovery. This article explores how mineral stability, energy-intensive processing, and impurity removal affect efficiency, product purity, and the path to industrial scale.
Critical Raw Materials
Spodumene and petalite are two important hard-rock lithium minerals, but their processing routes can differ significantly. This article compares their structure, thermal behavior, and leaching efficiency to answer a simple question: which one is easier to process?
Battery materials
Spodumene processing is not only about lithium recovery. Impurities such as quartz, feldspar, iron, sodium, calcium, magnesium, and aluminum-rich phases can strongly affect calcination, leaching, purification, and final product quality.
Critical Raw Materials
The α→β transformation is the key bottleneck in hard-rock lithium processing. It unlocks lithium recovery from spodumene, but requires energy-intensive calcination that strongly affects process efficiency and economics.
Battery materials
Turning spodumene into battery-grade lithium is far more than a single step, but it’s a complex chain of thermal and hydrometallurgical processes. This post breaks down the full journey from ore to high-purity lithium compounds.
Critical Raw Materials
Spodumene and brine follow fundamentally different paths to lithium — from energy use to processing complexity. Understanding these differences is key to evaluating the future of lithium supply.
