ABSTRACT. Spodumene is the main source of lithium among the lithium-containing minerals. A number of studies have been done on the extraction of lithium from naturally occurring α-spodumene as well as pre-treated β-spodumene and the effect of key factors that influence extraction and optimum processing conditions have been discussed.

The first condition is that the lithia content for spodumene should be a minimum of 3% and the lithia content for petalite and lepidolite should be a minimum of 2.5%. That's the first condition for the exportation of value-added lithium. And the second condition is that the prices which the exporter fetches should be a minimum of what is …
Once lithium is mined and processed, the powder concentrate undergoes a complicated chemical transformation to become a solid metal. Now it's ready to be used in batteries. Lee Powell/The ...
The composition of processing cost for extracting lithium from the above two ores is shown in Fig. 8, in which auxiliary materials such as fuel power and sulfate account for more than 75% of the processing cost. However, their production cost is highly related to the price of lithium concentrate.
If a concentrate project plans to produce lithium chemical products, it will have lower payable production compared with the original concentrate plans. We input these factors and the discount rate to the "average concentrate plant", the results showed that adding a hydroxide plant will generate more—although not significantly …
