The reverse flotation process is widely used in iron ore, bauxite, phosphate ore, and kaolin ore. The main components of iron reverse flotation froth are quartz and a small amount of hematite and magnetic iron ore. The flow chart of the reverse flotation production process of an iron ore dressing plant is shown in Fig. 3 (a).

Abstract This research aimed at recovering metals retained in the tailings from the flotation of copper (Cu) and cobalt (Co) ores conducted at the New Concentrator in Kipushi (NCK). Metals retention in the tailings (0.73% Cu and 0.37% Co) increased due to the removal of the gravity separation section from the processing circuit together with …

Floatation tailings (FT) are the main by-products of the hydrothermal sulfidation–flotation process. FT (FT1 and FT2) were obtained by treating two different neutralization sludges (NS) (NS1 and NS2). This paper quantitatively evaluated the environmental risks of heavy metals (Zn, Cd, Cu, Pb, and As) in FT versus NS. The total …
