Describe the principle of froth floatations process. What ...

The ore particles stick to the froth and rises to the surface, while gangue are left in water. The froth is skimmed off, collected and allowed to subside to get concentrated ore. This is especially suitable for sulphide ores.Fig. Froth floatation process.(a) Role of stabilizer: Stabilizers are used to stabilize the froth.

Extraction of Zinc: Froth Floatation Process, Roasting ...

The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K.

Froth flotation process and its application

Smelting: In this process heat is applied to the ore in order to extract the base metals like silver (Ag), iron (Fe), copper (Cu) etc. Often before roasting, the ore (generally sulfide ores) is partially purified using another important technique which is called froth flotation and it is the topic of our discussion as well.

What is the role of depressant in froth floatation process ...

The role of depressant in froth floatation process is to prevent certain type of materials from forming the froth with bubbles. For example, to separate two sulphide ores (ZnS and Pbs), NaCN is used as a depressant which selectively allows PbS to come with froth, but prevents ZnS from coming to froth. This happens because NaCN reacts with ZnS to form

2018-6-21  The iron ore extracted in the deposits, mostly by blasting, is initially very coarse and unwieldy, which gives this untreated rock the name coarse ore. After the coarse ore has been extracted, it is crushed directly at the deposits with the aid of cone crushers or jaw crushers to more manageable sizes of approx. 15 mm.
