Hard rock lithium deposits range in head grade from 0.4% Li 2 O in low grade deposits [ 4 ], to as much as 4% Li 2 O in higher grade deposits [ 5 ]. Hard rock lithium ore is used to produce either technical-grade or chemical-grade lithium concentrate, based on the intended end use, the impurities in the spodumene crystal structure …

The spodumene moves to a dryer and kiln that operate at about 1,000°C. This process converts the mineral into an easy-to-extract form using acid. This stage in the process also has the potential to release chemicals in the environment, some of which can be attributed to the fuel quality, calciner design, and emission abatement steps.
