Lithium Processing Plant, Equipment
Gravity-flotation-magnetic separation combined beneficiation: For lithium ore containing tantalum and niobium minerals, the combined process of gravity separation + flotation is generally used for processing. The lithium ore after gravity separation can enter the flotation stage after desliming treatment.
Flotation of copper oxide minerals: A review
The fresh copper oxide mineral surfaces exposed during crushing and grinding have a significant effect on subsequent flotation [23], [24], [25], [26].Many dangling bonds exist on fresh mineral surfaces because of destruction of the original lattice bonds, and the copper oxide mineral surface often shows strong polarity because of the …
