Collecting agent RS-530 (Fomol) is used as a collector of mineral floatation for selective collection of the following minerals: barite (BaS04) especially when linking together with calcite (СаС03), silica (Si02) and in cases when the ore has high content of clay fraction, celestine (SrS04), calcium sulphate (CaS04, 2H20), kainite (KCI.MgS04.3H20), anhydrate (CaS04), anglesite (PbS04), tinstone (Sn02), fluor calcareous (CaF2), and coal.
Rs-530 (Fomol) is effective in pH range 9-10. The quality of the collector is improved by adjusting the pH with soda ash and rock depression with sodium silicate. PC-530 is extremely selective for barite. The product shows low collective activity towards silica and calcite. This chemical is useful in cases when the abovementioned minerals are combined and the ore has a high content of clay fraction. Optimal consumption of RS-530 (Fomol) is 250 - 800 g/t,depending on specific flotation conditions
