sodium isopropyl xanthate technical Technical 90%

SODIUM ISOPROPYL XANTHATE

Molecular formula：(CH₃)₂CHOCSSNa

Application: Sodium isopropyl xanthte is an excellent collector for nonferrous metal sulfide ore with good selectivity and has strong collecting ability. Widely used in the copper, molybdenum and zinc sulfide ore. Better in floatation of the mock gold. It could improve the gold recovery when using in the gold and copper mine. It could make good result in the copper and lead oxidized ore. Normally used in rough selecting and scavenging
