Apr 11, 2019 · 4. Xanthate Appliion in Galena Froth Flotation. The surface of galena is hydrophobic, so it's easy for flotation. Xanthate is the common collector for the flotation of galena. When the pH is high, the galena is easily floated by the ethyl xanthate. The optimum pH for flotation is 78, which can usually be adjusted with sodium carbonate.

Dec 06, 2019 · Froth floatation method : This method is used for removing gangue from sulphide ores. In this powdered ore is mixed with collectors ( pine oils, fatty acids etc.) and froth stabilisers ( cresols, aniline) which enhance nonwettability of the mineral particles and froth stabilisation respectively.
It is an ideal method for the concentration of sulphide ores because the froth flotation method is based on the preferential moisturizing properties of the frothing agent and the water, and the sulphide particles of the ore stick to the oil droplets and start rising in the form of the froth.
