Recycling spent batteries to recover their valuable materials is one of the hot topics within metallurgical investigations. While recycling active materials (Li, Co, Ni, and Mn) from lithium-ion batteries (LIB) is the main focus of these recycling studies, surprisingly, a few works have been conducted on the other valuable metals. Copper and aluminum …

The next stage after froth flotation is the thickening stage. The froth is poured into large tanks called thickeners. The bubbles break and solids from the froth solution settle at the bottom of the tank. The solids are then filtered to remove excess water, which can be reused in processing additional batches of sulfide ore.
