KOHAD Hindustan Zinc Ltd., Zawar Mines, Udaipur - 313 901 ABSTRACT Flotation process, patented in the year 1906, was originally developed for mineral industry to recover values from high grade tailings of gravity separation plants. This technology has acclaimedWhy Only Sulphide Ore Is Concentrated By Froth Flotation,Such a separating process is froth flotation, and in the case of iron and other sulphide containing ores, it is usual to float the value metals off and depress the bulk of the iron sulphidesAbout 48% of the total pyrrhotite in the ore was reported in the copper-nickel concentrate, and only 52% in the tailing.Which of the following ores is not concentrated by froth,,Solution: Froth floatation method is commonly used for the concentration of the low-grade sulphide ore. The principal is based on the fact that gangue and ore particles have a different degree of wettability with water and pine oil. The ore particles are wetted by oil whereas gangue particles are wetted by water.,
