Sodium Ethyl Xanthate

FORMULA	:	C2H5OCS2Na
ORIGIN	:	China / Europe
PACKING	:	850kg/wooden Box;120 kg/drum
APPLICATION	:	Used in the flotation process...

Short description

Formula: C3H5NaOS2, C2H5OCSSNa CAS number: 140-90-9 Appearance: powder, light yellow Packing: 50kg / bag or 120kg / drum Origin: China / Europe Application: Sodium ethyl xanthate is predominantly used in the mining industry as flotation agent for recovery of metals, such as copper, nickel, silver or gold, as well as solid metal sulfides or oxides from ore slurries. This application was introduced by Cornelius H. Keller in 1925. Other applications include defoliant, herbicide and an additive to rubber to protect it against oxygen and ozone. The mechanism of flotation enhancement is as follows. The polar part of xanthate molecule attaches to the ore particles with the non-polar hydrocarbon part sticking out and forming a hydrophobic layer. Then the particles are brought to the water surface by air bubbles.
