The spodumene grains present were found them to contain from 5.55% to 7.03% Li 2O. The relatively low grade of the ore and variation in lithium content of the spodumene, also being relatively low, would normally present significant difficulties in the recovery of the spodumene and in preparing a marketable concentrate grade.

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.
