froth flotation and roasting of zinc

  • 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

  • Q1 How is zinc extracted from zinc blende?Ans: The steps involved in the extraction of zinc blende is 1 The concentration of the ore through the Froth Floatation Method 2 Conversion ofQ2 Which ore is used to extract zinc?Ans: The chief ore used to extract zinc is zinc blende (ZnS)Q3 What is the first process of zinc extraction?Ans: The first process in the extraction of zinc is the concentration of the ore, which is done by the Froth Floatation method It is based on theQ4 What is the main ore of zinc?Ans: The main ore of zinc is zinc blende (ZnS)Q5 Where is zinc used?Ans: Most of the zinc is used in the galvanization of iron It is also used for the production of zinc oxide (ZnO) It is also used for alloying puQ6What are 3 properties of zinc?Ans: Zinc is a trace transition element It is brittle and crystalline at ordinary temperatures but ductile and malleable between 110∘C to 150∘C TQ7 What is the role of zinc metal in the extraction of silver?Ans: In the extraction of silver, zinc metal acts as the reducing agent and reduces silver from its cyanide complex to its elementary form 2[Ag(CN
