Light-yellow crystals. Soluble in water.
Deliquescent, decomposes 150C.
Control of annual weeds in bean and pea fields.
Proxan Sodium is used in preparation method of Silica with low heavy metal content and high adsorbability, and its application as carrier of liquid animal nutrition agent of feed additive. used as an herbicide, fortifying agent for certain oils, and flotation reagent for base and precious metal ores; Used as a rubber curing agent and antioxidant, pesticide and fungicide, and high-pressure lubricant additive; Also used for analytical procedures, for froth flotation in soils contaminated with mercury, and in the past as an intermediate for saccharin.
Sodium isopropyl xanthate is used as a collector for sulphide minerals in alkaline flotation circuits. Use in acid circuits will lead to the decomposition of the product. It is widely used for copper, it is effective in native metal flotation, and is widely used in precious metal flotation and the selective flotation of polymetallic base metals.
Sodium isopropyl xanthate can be used as a collector for oxide minerals of base metals which have previously been treated by sulphidisation.
Sodium isopropyl xanthate can be used in either rougher or scavenger flotation.
Moderate fire risk. Irritant to skin and
mucous membranes.
Flammability and Explosibility
Flammable
It crystallises from ligroin/ethanol.
Dosage rates of sodium isopropyl xanthate vary from 15 to 150g/t of ore. Sodium isopropyl xanthate is normally added to the pulp before flotation as an aqueous solution of between 3 and 10% by weight. It is recommended that solutions be stored for no longer than 3 days due to the formation of carbon disulphide.
