Assertion : Sulphide ores are concentrated by Froth Flotation method. Reason : Cresols stabilise the froth in Froth Flotation method.

Sulphide ores are concentrated by froth floatation process.

Which of the following ores are concentrated by froth floation ?

Why is pine oil used in froth floatation method?

Which one of the following ore is best concentrated by froth floatation method?

The 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+3O_3 80% rarr 2ZnO+2SO. ZnO+H_2SO_4 100% rarr Zn SO_4+H_2O and 2ZnSO_4+2H_2O 80% rarr 2Zn+2Hn+2H_2SO_4+O_2 . The number of moles of ZnS required for producing 2 moles of Zn will be :
