1. Common types of lithium ore
1) Spodumene, mainly lithium-containing primary ore, ore Mohs hardness 6 (limestone is 3-3.5, quartz is 7), density 2.7-2.9t/m³, grade mainly depends on lithium oxide content, generally 1-6 %;
2) Lepidolite, mica-like minerals, another major category of lithium minerals, has low hardness and low density, and the content of lithium oxide is generally lower than that of spodumene;
3) Lithium in salt lakes is mainly sourced from lake water with high salinity and does not need to be broken.
