Sodium Iso-butyl Xanthate

Dscription: powder and pellet form or Clear orange liquid with an unpleasant odour

Usage:Mining industry flotation reagent
Minor uses include curing and vulcanization of rubber; as an antioxidant for rubber; as a erbicide, pesticide and fungicide;as a high-pressure lubricant additive; as a fortifying agent for
certain oils; for analytical procedures; and in a froth flotation process for soils contaminated with mercury

 

XANTHATES 
Application
Xanthates are used for the flotation of sulphide and sulphidized oxide ores(sulphidizer:sodium sulphide(Na2S) or hydrosulphide(NaHS). The activity of the xanthates increases with increasing chain length of the alky group R; the selectivity decreases in accordance with increased chain length. Xanthates are often used in combination with other reagents such as dithiophosphates or thionocarbamates, often added to the scavenger circuit to improve the total recovery. They are normally used in aqueous solutions.
Xanthates undergo hydrolysis in the acid pH range, and are therefore preferred for flotation in alkaline pulp streams..
The flotation results can be improved by simultaneous use of xanthates together with dithiophosphates.
Xanthates are available as powder or in pellet form and with an active matter content of 85% and 90%
