Flotation is the main process for the recovery of barite from ores [4]. 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 ...
