Acid roasting of spodumene: Microwave vs. conventional
The use of microwave ovens in the acid roasting of spodumene as part of the process for lithium extraction was investigated and compared with conventional furnace heating. The effects of various key process factors were evaluated. Conventional acid roasting of 5 g of β-spodumene at 250 °C for 60 min was highly effective in extracting lithium ...
