Product Description

The Purity of The Sodium Ethyl Xanthate Series is More Than 90％ Pallet

Product information

Light yellow powder with pungent smell can be dissolved in water,alcohol,etc,and can form insoluble compounds with cobalt,copper,nickel and other metal ions. Hazard Code:R36/37/38:irritating to eyes,respiratory tract and skin.Molecular formula:C3H5NaOS2,Molecular weight:144.19,Density:1.558.Xanthate is widely used in rubber industry as curing accelerator,Sodium ethyl xanthate as precipitant and colorimetric agent for copper and nickel in analytical chemistry,copper and nickel in solution in metallurgical industry,Sodium cellulose xanthate as artificial fiber and starch xanthate as sewage treatment.At the same time,xanthate is the most widely used collector in the world,especially in the process of heavy metal sulfide ore dressing and flotation,in addition,it is also a commonly used extractant in precious metal recovery.Xanthate is a yellow powder solid at room temperature,and its color is often deepened due to the presence of impurities.It is toxic,flammable,hygroscopic,unstable and soluble in water,acetone and corresponding alcohols.The pure product has a slight odor,which is the smell of the product after its slow decomposition.Because the existence of impurities often accelerates its decomposition,it generally has an unpleasant smell.

Main purpose

Sodium ethyl xanthate is the best collector in xanthate series. It can be widely used in the preferential flotation of easily floatable or complex non-ferrous sulfide ores.Sodium ethyl xanthate can be also be used with sulfurizer for flotation of copper and lead oxide ores.Sodium ethyl xanthate can also be used as precipitation agent of hydrometallurgy(such as purification of zinc electrolyte)and accelerator of rubber vulcanization.

Chemical properties

White or yellowish needle crystal with mercerization.It has a pungent odor.Soluble in water and ethanol.Use as collector of nonferrous metal ore flotation.
