Froth floatation process used for the concentration of sulphide ore :

is based on the difference in wettability of different minerls

uses sodium ethyl xanthate, `C_(2)H_(5)OCS_(2)Na` as collector

uses NaCN as depressant in the mixture of ZnS and PbS when ZnS forms soluble complex and PbS forms froth

All are correct statements
