Jul 17, 2017However, lepidolite is not as rich in lithium as other lithium-bearing silicate minerals (particularly spodumene) often found in the same rock so it is not the ore of choice. Research is ongoing because, as the demand for lithium continues to rise, lithium ores that are more expensive to process could become economically viable.
