A novel approach for flotation recovery of spodumene, mica and feldspar
In this paper, a complete scheme aimed at improving the flotation performance of spodumene and comprehensively recycling mica and feldspar from lithium tailings in an economical and environmentally friendly way is put forward. The flotation performance of spodumene and feldspar with four size ranges (0–19, 19–38, 38–45 and …
