Flotation Circuits. Flotation circuits are typically comprised of rougher, scavenger and cleaner flotation banks. Rougher and scavenger banks are focused on recovery and thus provide maximum residence time. Rougher banks can be large with the number of cells being 5 or greater. Scavenger cells are the last line of defense for avoiding losses.

Sodium oleate and pine oil are typically used as collector and frother in barite flotation at pH 10 [5,6]. However, oleate is sensitive to slimes [7], low temperatures [8,9], and hard-water ions [10]. In this regard, many other collectors have been explored in barite flotation. Barite is either prefloated
Barite pre-flotation of natural fines (fines produced after rod milling) was eliminated at Bunge's Araxá concentrator when the mechanical cells circuit was replaced by a columns only circuit.
