Function of potassium ethylxanthate in froth floatation process is to make the ore
1 hydrophobic
2 hydrophilic
3 heavier
4 lighter.
Explanation:
The function of potassium ethylxanthate in forth floatation process is to make the ore water repellant i.e., hydrophobic.

Which is used as flux in metallurgy?
1 \(\mathrm{CaF}_{2}\)
2 \(\mathrm{SF}_{6}\)
3 \(\mathrm{UF}_{6}\)
4 NaF
Explanation:
Industrially, \(\mathrm{CaF}_{2}\) is used as a flux for smelting and in the production of certain glasses and enamels.

Which among the following ore is concentrated by froth floatation process?
1 Bauxite
2 Dolomite
3 Galena
4 Diaspore
Explanation:
Galena \(\mathrm{(\mathrm{PbS})}\) ore is concentrated by froth floatation process. This process is used for the concentration of sulphide ores. In the given option, galena \(\mathrm{(\mathrm{PbS})}\) is only sulphide ore. This method is based on the preferential wetting properties with the frothing agent and water.

Commonly used collectors in froth floatation method are I. Pine oil II. Coconut oil III. Fatty acids IV. Xanthates Choose the most suitable set containing option from the choices given below.
1 I,II and III
2 II, III and IV
3 I, III, and IV
4 I, II, and IV
Explanation:
Commonly used collectors in the froth floatation method are pine oil, fatty acids, xanthates (like amylxanthate). So, the option (3) is correct.
