potassium amyl xanthate copper flotation
Potassium Amyl Xanthate Structure formula C5H11OCSSK Appearance Light yellow or gray with pungent powder or granules soluble in water Principal uses： Potassium amyl xanthate is a strong collector it is mainly used in the flotation needed without the need for strong selective nonferrous metal mineral flotation For example it is the oxidationThe xanthates cause the minerals to attach themselves to air bubbles and then float to the top of the flotation cell As values reach the surface, the bubbles form a froth that overflows into a trough for collection The residual may be reused for additional recovery or removed for disposal Most of the xanthate is consumed in the processPotassium Amyl Xanthate, What is Potassium Amyl

Selective flotation of sodium chloride from sylvinite ores
This pulp is composed largely of the flotation solution and solid potassium chloride, but there are almost invariably small particles of sodium chloride attached to some of these particles of potassium chloride and these attached particles are floated to the surface in the cell 8 and delivered into the trough 8', additional fatty acids orCalcite flotation in acidic media is a difficult task due to the solubility of calcite and consequently the release of calcium ions in the flotation pulp In addition, the interaction of calcium ions with the flotation reagents requires the correct selection of these reagents In this study, potassium oleate and potassium dihydrogen phosphate (KH2PO4) were used asCalcite Flotation in Potassium Oleate/Potassium

Potassium Amyl Xanthate, What is Potassium Amyl
The xanthates cause the minerals to attach themselves to air bubbles and then float to the top of the flotation cell As values reach the surface, the bubbles form a froth that overflows into a trough for collection The residual may be reused for additional recovery or removed for disposal Most of the xanthate is consumed in the processThe same approach can be use to explain the flotation response of the potassium double salts; schoenite, kainite, and carnalliteIn addition, the sign of the surface charge of schoeniteThe flotation chemistry of potassium double salts
