  • Question 1
    1 / -0

    Spelter is

    Solution

    Spelter is impure zinc.

    The correct answer is: Impure zinc

     

  • Question 2
    1 / -0

    In which of the following minerals, aluminium is not present?

    Solution

    Aluminium is not present in fluorspar. Fluorspar is CaF2 (calcium fluoride).

    The correct answer is: fluorspar

     

  • Question 3
    1 / -0

    Process which is generally used for extraction of magnesium from its Ore.

    Solution

    Generally magnesium is extracted by the electrolysis of its fused salt.

    The correct answer is: Electrolysis of its fused salt

  • Question 4
    1 / -0

    The froth - floatation process for concentration of sulphide ores is based upon

    Solution

    On being preferentially wetted by oil, the ore particles rise to the surface in the form of froth and from there we can separate them.

    The correct answer is: preferential wetting of ore particles

     

  • Question 5
    1 / -0

    Find the ore that is not concentrated by Froth floatation process.

    Solution

    Pyrolusite is an oxide ore. Froth floatation process is generally used for concentration of sulphide ores.

  • Question 6
    1 / -0

    The method which is used to remove lead present in silver is.

    Solution

    For purification of silver containing lead as impurity we use the cupellation method. 

    The correct answer is: cupellation

     

  • Question 7
    1 / -0

    What is the reason of rise of ore particles to surface during concentration by Froth floatation process?

    Solution

    Ore particles are hydrophobic and hence rise with foam to the surface.

    The correct answer is: Ore particles are hydrophobic

  • Question 8
    1 / -0

    The process that can be used for refining tin and lead is

    Solution

    Liquation process can be used for refining tin and lead because they have low melting points.

    The correct answer is: Liquation

     

  • Question 9
    1 / -0

    Which of the following processes is used to get pure metal from impure zinc spelter?

    Solution

    To get pure zinc from spelter (i.e., impure zinc) we generally use fractional distillation process.

    The correct answer is: Fractional distillation

     

  • Question 10
    1 / -0

    High purity copper is obtained by

    Solution

    High purity copper is obtained by electrolytic reduction.

    The correct answer is: Electrolytic reduction
