In the flotation process, the particle size has a great influence on the recovery of metal particles with high specific gravity. Materials in the size range of −300 + 20 μm are generally preferred for an effective flotation process in primary ores. Copper particles in the S-LIBs have a flat-shaped monolayer (foil) structure.Web

Herein, a froth flotation process is developed to separate pristine lithium nickel–manganese–cobalt oxide (LiNi 0.333 Mn 0.333 Co 0.333 O 2, NMC111) and lithium manganese oxide (LMO) materials. The flotation results show that with multiple stages of the separation processes, a satisfactory separation is achieved with 95% grade or above …Web

A selected froth product was used as feed for nickel slag cleaning process, and the recovery of metals from a slag (80%)–froth fraction (20%) mixture was investigated in an inert atmosphere at 1350 °C and 1400 °C at varying reduction times. The experimental conditions in combination with the graphite allowed for a very rapid reduction.Web

The entrainment process during flotation is influenced by a number of factors in the pulp and froth. Among them, frothers can result in a great variation in the amount of gangue minerals reporting to the concentrate (Rahal et al., 2001; Melo and Laskowski, 2007; Comley, 2012; Wiese and Harris, 2012; Kracht et al., 2016).Web
