Cassiterite S n O 2 (oxide ore), and Magnetite F e 3 O 4 (oxide ore) are not sulphide ore. The froth flotation process is used to concentrate sulphide ores, based on preferential wetting properties with frosting agent and water.
Learn MoreOre Concentration by Froth Flotation. Remember that only 0.67% of the ore is copper. The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and ground-up limestone) to ...
Learn MoreKCET 2009: The ore that is concentrated by Froth Floatation process is (A) Bauxite (B) Malachite (C) Zincite (D) Cinnabar. Check Answer and Solution f
Learn MoreApr 06, 2020· In ore/mineral beneficiation, froth flotation is a method by which commercially important minerals are separated from impurities and other minerals by collecting them on the surface of a froth layer. Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out.
Learn MoreThe chief ore of Zn is the sulphide, Zns. The ore is concentrated by froth floatation process and then heated in air to convert ZnS to Zno. 2ZnS + 30,- 80% 2 ZnO + 250 ZnO + H2SO, - 100% → ZnSO, +H, O
Learn MoreChoose the correct statement(s) for froth flotation process, which is used for the concentration of sulphide ore. a) It is based on the difference in the ability of different minerals to become wet. b) It uses sodium ethyl xanthate, C 2 H 5 O C S 2 N a as collector.
Learn MoreFroth Flotation Method: This method is mainly used to remove gangue from sulphide ores. The ore is powdered and a suspension is created in water. To this are added, Collectors and Froth Stabilizers. Collectors (pine oils, fatty acids etc) increase the non-wettability of the metal part of the ore and allows it to form a froth.
Learn MoreThe three ores which are concentrated by froth-floatation process are: (i) Copper pyrites (CuFeS2)(ii) Zinc Sulphide (ZnS) (iii) Silver glance (Ag2S).Depressants are used to prevent certain types of particles from forming the froth with bubbles.Example: NaCN is used as a depressant in the separation of ZnS and PbS ore. NaCN forms a layer of Zinc complex Na2 Zn(CN)4 on the surface of ZnS and ...

Learn MoreThe physical methods include traditional hand picking, hydraulic washing, magnetic separation, froth floatation for the concentration of ore. Hand picking. It was the traditional method of concentrating ore directly with hands. In this method, ...
Learn MoreAt this step, the frother (for example, fuel oil) is added to the ore slurry to form stable froth and air bubbles. Iron oxide particles stick to the air bubbles and float. Floated and concentrated iron ore slurry is then skimmed from the surface of the bath, and water is removed using a filter press.
Learn MoreFroth floatation is method that is used to separate materials on the basis of their orientation towards water i.e. hydrophilic or hydrophobic. Various types of sulphide ores such as galena (PbS) are concentrated using froth floatation method in presence of alkali and CuSO4 which acts as depressants and activators respectively.

Learn MoreThis method is based on the principle of the difference in the wetting properties of the ore and the gangue particles with the water and oil. This method is used for that metals whose ore gets preferably wetted by the oil and the gangue by the wat...
Learn MoreThe ore which can be attracted by the magnetic field can be concentrated by the process of magnetic separation. Among the ores mentioned in table 6.1, the ores of iron such as haematite (Fe 2 O 3 ), magnetite (Fe 3 O 4 ), siderite (FeCO 3 ), and iron pyrites (FeS 2 ) can be separated by the process of magnetic separation.

Flotation, as the term is applied to ore concentration, means the separation of. 7.1 The quantity of oil necessary in any froth-flotation operation. grade of concentrate and a high percentage of recovery cannot be made in.
Learn MoreThe froth thickness and this washing process enable a higher enrichment of ore in the froth, improving the quality of concentration and the recovery. The froth that is rich in hydrophobic material is discharged in the launders. In direct flotation, this froth corresponds to the concentrate.
